量化投资之网格交易策略
一、网格交易策略
这是一种仓位策略，用于动态调仓。该大法秉持的原则是”仓位策略比选股策略更重要”。
所谓网格交易法（grid trading method），也称鱼网交易网，指以某点为基点，每上涨或下跌一定点数挂一定数量空单或多单，设定盈利目标，但不设止损，当价格朝期望方向进展时获利平仓，并在原点位挂同样的买单或卖单。
基本概念
1、底仓价：价格的标准线，建仓和调仓的重要依据。
2、低吸高抛：仓位控制贯彻低吸高抛，绝不追涨杀跌。下面举个例子：
操作：在底仓价的附近，我们根据网格的大小，比如每跌3%按仓位买入（第一档：买40%，第二档：买30%，第三档：买20%，第四档：买10%）。
要注意的是，这里买卖不是绝对的定量，而是调仓到对应仓位。如果第一次跌破3%，而后上涨到5%时，是不操作的，因为下跌时只建了40%的仓，而上涨5%的仓位是60%，不够抛出。
二、网格交易的特点和局限
1、底仓价格设定：若没有在安全边际内设定底仓价格，而在估值顶部设立底仓价格，则风险极大，会造成很大损失。
2、牛市表现不佳：分散的仓位策略，没有依据价格形态来修改网格，都可能在牛市中跑输大盘，降低贝塔的代价就是阿尔法也较低。
3、买卖规则不灵活：可能使一些重要的突破支持或阻力位置的买卖点被忽略在网格之外。
三、策略步骤
1、选股
重点行业：I64 互联网和相关服务，I65 软件和信息技术服务业
低估值PE小：PE<50
小市值：分行业按市值排列选市值小的30只
高波动：分行业在市值最小的30只中选出过去一年波动率最大的5只股票
注：每3个月按上述条件更新一次股票池，更新时不在新股票池的股票全部清仓。
2、网格
[-3%买，5%卖]、[-5%买，10%卖]、[-8%买，15%卖]、[-12%买，20%卖]
四种大小的网格都会相应尝试一下看看效果。
3、资金安排：在仓位控制时，满仓的概念是（总资金/股票池总数*2.5）
注：后面的乘数是为了提高资金利用率，因为3个月的周期内可能不是每只股票都能达到满仓。
四、结论
1、【熊市】：选取2015-6-1至2016-1-26，大网格-12%买，20%卖。最好的结果是半年多盈利20%（大盘同期大跌35%），年化40%；
2、【长周期】：选取2010-1-1至2015-12-31日，中网格-8%买，15%卖。最好的结果是6年241%（大盘同期4%），年化23%；
3、【震荡期】：选取2012-1-1至2013-112-31日，小网格-3%买，5%卖。最好的结果2年68%（大盘同期-0.5%），年化29.6%。

As I’ve mentioned, there isn’t a perfect hack squat to back squat ratio.
This simply comes down to the reality that you’ll hit nearly each muscle in your
decrease physique if you squat. We all usually view squats as the major lower physique exercise,
often referred to as “The King of Lower Physique Exercises”.
Rogue has made a real standout leg press for many who need and might take the punishment.
A word of recommendation, though- every unit is shipped totally assembled, so you’ll
wish to put together upfront. It’s immovable
as a tank, assured to last a lifetime and will definitely
be your best good friend in relation to core and lower body growth.
But wait, how about health club gear that tackles an oft-forgotten but essential facet of training?
Squats will often do the trick, however squats can be exhausting on the decrease back and are
tough if you have a leg injury. While you may not want the strongest leg press machine available on the
market, this list offers all kinds of options that may allow you to smash your health targets.
As you invest in home fitness center workout equipment, including the
proper leg press machine is probably high in your precedence listing.
Researchers had been in a place to again this up, discovering that trunk activation was overall considerably greater in again squats in comparability with hack squats1.
Whereas there are many causes to love the hack squat machine, there
are some situations where it’s not for everyone. Hack squats are an alternative
for lifters who simply need a method to target their quads without placing a heaping ton of weight on their back.

pretty acquainted with barbell squats, lunges and deadlifts.
Probabilities are you already have them firmly
rooted in your training plans. In The End, there is not any definitive “winner” in the hack squat vs pendulum
squat debate. [newline]Both exercises supply distinctive advantages and drawbacks,
and the only option is dependent upon your particular person targets and preferences.
The barbell front squat is a superb various that mimics
the quad-dominant nature of the hack squat. It also doesn’t strain the lower back as a lot as the traditional barbell back squat.
This variation shifts the focus to the glutes and hamstrings as an alternative of the quads.
The best option finally is determined by your individual objectives and desires.
If you prioritize quadriceps growth and prefer a
extra managed motion, the hack squat could be extra appropriate.
If you seek functional strength, full-body engagement, and a larger challenge, the normal squat is the better choice.
The hack squat is probably pretty a lot as good as squats in relation to
building your leg muscles and growing your power in the decrease physique.
However, hack squats won’t provide the stability and stability coaching that free barbell squats
do. A good workout for strengthening the muscle tissue around your legs, particularly the quadriceps muscles, is the hack squat.
The hack squat is a squat variation that uses either
a devoted machine, the hack squat machine or utilizing a Smith Machine.
If you’ve carried out a Smith Machine squat, then you
are in a place to do the hack model. You do not want to be fully
leaning on the bar of the machine, however this position will allow
you to target the quads extra effectively.
If you are restricted to dumbbells, then the goblet squat might be a
wise choice to add into your routine.
There are, equally, some products available on the market that don’t match
shorter folks very nicely. Since the rise of the (resistance) machines, hack squats have nearly
exclusively been performed on machines. It Is extra handy, it’s less complicated to load up and you’ll handle heavier
hundreds in a safer fashion making it more useful in just about each means.
While the hack squat can be a good different for these with back points or restricted mobility,
it shouldn’t be thought of a direct substitute for the traditional squat.

sought-after anabolic steroid known for its performance-enhancing
effects? Whether you’re an skilled athlete or a health enthusiast trying to take your coaching to the following stage, buying Anavar requires careful consideration.
But, if you should burn undesirable fats and keep lean and powerful muscular
tissues, Anavar would work great. Anavar just isn’t widely generally known as a strength-enhancing steroid, nevertheless it excels
on this regard, and one purpose is that the ATP uptake in muscle cells is increased.
You’re likely to see a great improvement in the amount of weight you can raise when utilizing Anavar.
An Anavar cycle will normally cost significantly greater than different oral steroids (like Dianabol, for example).
And the most well-liked injectable steroids will always be cheaper – usually much
cheaper than Anavar. Some of these customers will stop utilizing the steroid for
these causes. Others discover that testosterone suppression is a lot greater than expected.
The constant optimistic feedback displays
the results users are experiencing and the final satisfaction with the
product. Anavar can even cause adverse effects that may cut back
well-being in users, similar to male sample baldness or
benign prostatic hyperplasia. Also, users are suggested to get their ALT and AST levels checked pre-cycle

questions and sharing data on prohormones and designer steroids.

adverse results on well being, and its long-term
use might damage very important organs. The CrazyBulk
range is terrific, and Anvarol is considered one of their star
products. Anvarol brings about a very watered-down model of the
benefits enjoyed by anyone taking Anavar. If you want a pure, over-the-counter, legal, moral force multiplier to work a little
like Anavar, though far much less potently, you’ll do properly looking at Anvarol by CrazyBulk.
Even average PEDs like Anavar convey too many disagreeable unwanted side effects
and moral considerations to make them a tenably good
thought.
I suppose I’ll go to eight weeks on Anavar if I’m taking not more than 50mg.
I wouldn’t need to transcend six weeks if any greater than 50mg
is being taken (rarely). This does mean you’re using
Anavar basically as a pre-workout steroid. In my experience, this is the easiest
way to use Anavar as a result of we don’t want (or even want) to maintain constant ranges of this liver-toxic steroid (no matter how mild) 24 hours
a day. Females running a first Anavar cycle ought to
begin very low to judge side effects. 5mg per day is known to be well tolerated in scientific use by
many feminine sufferers.

back toxicity. Equally, virilization, cholesterol alterations, and liver harm stay attainable.
Anavar, in any other case often recognized as
oxyandrolone, is among the many most generally used anabolic steroids within the fitness and bodybuilding world.
Praised for its mild but efficient properties, it has gained vital attention from athletes, bodybuilders, and people seeking efficiency
enhancement. For this cause, Anavar is kind of at all times used as
a slicing steroid, which is the purpose it excels at.
Fat loss remains to be more probably to happen for girls (unless your food plan could be very calorie-heavy).
The fat loss mixed with lean features may end up in an general gain in physique weight, however importantly,
it shouldn’t be water weight, and the positive aspects should be all muscle.
As A Substitute, they are making an attempt to detect other medication used, such as
marijuana, cocaine, amphetamines, and opiates. However, they’ll take a look at for steroids, particularly in instances the place
they are identified to be rife in a specific unit or if there might be another excuse to
suspect somebody of using them. Alcohol has a adverse impact on cortisol ranges (35);
thus, fat-burning might turn out to be inhibited.
Moreover, cortisol is a catabolic hormone, which means heavy alcohol consumption could cut back muscle mass.
For maximum outcomes, customers should decrease alcohol consumption throughout a cycle.
However, low quantities of alcohol are unlikely to affect a user’s outcomes significantly.
This means that women who use Anavar ought to have regular liver
operate checks to monitor their liver well being. Anavar is
thought to increase stamina and endurance, allowing customers to push themselves additional during workouts and bodily activity.
This elevated level of energy may help women reach their objectives faster,
whether it’s weight reduction or improved power. In our
expertise, customers will encounter all of the effects of injectable trenbolone,
however with notably enhanced results and significantly more hepatotoxicity.
Oral trenbolone is perhaps the most harmful anabolic
steroid we’ve come across, with the dangers being very high for many
users (psychologically and physiologically).
As with the chopping cycle, 10mg of Anavar per day is a good start line.
Var injection is very regarded for its capability to increase
nitrogen retention within the muscle tissue, which is essential for protein synthesis and muscle growth.
By optimizing nitrogen stability, Anavar injection helps athletes and bodybuilders recuperate extra successfully from
intense exercises and construct lean muscle tissue.
Nevertheless, in my view, the finest way to keep away from any
and all unwanted side effects are to keep away from Anavar at all
value. Lastly, you need to just keep in mind to are taking Anavar on the proper time of day.
If you select to inject Anavar, you want to make sure that you are injecting it right into a
muscle that has loads of blood move. The finest muscular tissues to inject Anavar into are the glutes,
quads, and delts.
We discover that an Anadrol cycle provides considerably extra lean muscle tissue than an Anavar cycle.
However, Anadrol’s fat-burning effects usually are not as pronounced
due to Anavar’s positive results on insulin sensitivity and T3 (triiodothyronine).
To put this dosage into perspective, superior male steroid
users typically take 50–100 mg/day for eight weeks. A imply net achieve of 8.5 cm over the projected last
height was achieved.

for athletes and bodybuilders. General, Anavar is a well-liked selection for men who wish to enhance their physiques without putting their well being

It additionally will increase insulin-like
development factor-1 (IGF-1) expression, additional supporting muscle repair
and hypertrophy.
Testosterone can clinically be prescribed to women with deficiency, which could
be skilled during menopause. However, in our expertise, testosterone increases the danger of virilization, and thus it is not an optimum medicine for women. We typically see Anavar shift cholesterol levels, reducing HDL and increasing LDL; due to this fact, a modest improve in blood stress should be anticipated (7).
Anavar (oxandrolone) is an oral anabolic and one of many least toxic steroids we now have seen (alongside
testosterone).
Ladies typically take Clenbuterol when slicing to raise their metabolism
and enhance fats burning (5), through the process of thermogenesis.
Clenbuterol isn’t a steroid however as a substitute a bronchodilator (6), which means it
does not have an result on hormones in the identical means as AAS.
Dr. Thomas O’Connor states that Primobolan impacts girls differently, with
some being very happy with its effects (even when utilized in stacks alongside Anavar).
This additional fluid will increase blood viscosity, resulting in the heart having to pump
harder, causing a rise in blood pressure and restricted blood circulate.
Anavar just isn’t widely often recognized as a strength-enhancing steroid, but it excels
on this regard, and one reason is that the ATP uptake in muscle cells is elevated.
You’re more probably to see a fantastic improvement within the amount of weight you can raise when utilizing
Anavar. An Anavar cycle will normally price significantly greater than other oral steroids (like Dianabol,
for example). And the most popular injectable steroids will at all times be cheaper
– typically less expensive than Anavar. Most male opponents could have between 3%
and 5% body fat during competitions. Bear In Mind that these are probably the most extreme users, and
they’re likely to use different compounds alongside or
as a substitute of Anavar. It has a high anabolic ranking, however this doesn’t translate into highly effective anabolic results that may rival
these of true bulking steroids (which are virtually all the time injectables).
Anavar is an oral steroid that was first developed within the 1960s
by Searle Laboratories. It had initially been indicated for medical situations
similar to muscle wasting, weight loss due to chronic diseases, and extreme burns.
Its effectivity in enhancing lean muscle development without severe androgenic side effects
has made it a darling for many fitness fanatics. Dbol can solely be run for short cycles
when you don’t wish to stuff up your liver massively.
Anavar will still have an result on liver enzymes,
however to not the level that Dbol and other harsh orals
do. Anavar can additionally be a compound that can be used by females at decrease doses with a a
lot decrease chance of virilization effects compared with different steroids.
Winstrol is far harsher on the liver compared to Anavar, although they’re
both oral steroids.

Winstrol works by increasing protein synthesis and reducing muscle catabolism.
Many bodybuilders combine these two together when trying to burn fat and hold on to muscle mass.
Although winstrol/clen is used predominantly to burn fat, a person can usually
appear to be they’ve gained a major quantity of muscle after a cycle.
Although Winstrol is predominantly used as a chopping agent, its anabolic results and talent to add
lean mass should not be underestimated. Uniting two complementary compounds can result in a exceptional collaboration,
and that’s precisely what occurs when Winstrol and Anavar be a part of forces.
By bringing Stanozolol and Oxandrolone together in a stack, fitness aficionados
access a strong software for sculpting their dream physique.
The secret is in understanding the distinctive attributes of each compound and the way they interact to create a synergistic effect.
Anadrol stacked with another steroid may go away a girl unscathed in regards to masculinization; however, we
see testosterone suppression, liver pressure, and blood stress as probably
issues. We have found 25–50 mg of DHEA, taken daily for
4 weeks, help within the recovery of low testosterone ranges in females.
There’s also a danger to the liver from Anavar, which can cause liver harm.
Taking it in excessive doses for a very long time can result in severe liver points, like tumors or peliosis hepatis.
Nonetheless, opposite to anavar, wild yam root HAS shown to increase HDL cholesterol levels and improve
cardiovascular health.
Nevertheless, Anavar is taken into account to be simpler at
burning fats in comparability with Masteron. This is
as a result of Anavar has the next metabolic price, which suggests it
may possibly assist burn fats more efficiently.
The weak hepatotoxicity of Anavar in relation to the liver is
unique as it is an oral c-17 alpha-alkylated steroid.
Such oral compounds are usually notorious for inflicting jaundice, hepatic peliosis, or liver failure.
Rising the day by day dose of Anavar to 40mg per day, however, leads to
solely a slight change in your lipid profile. It is mildly toxic to the liver
mainly as a end result of part of it is metabolized by the kidneys
as properly, thereby sharing the load on the liver. Studies have proven that kidneys
also process Oxandrolone which is evidenced by over 1/3 of the compound being present in urine.
One of the problems with Winstrol is that it results in extreme
intracellular water depletion which tends to make your muscular tissues
look flat. However, Winstrol is a more potent steroid
and it could help you achieve close to 15 lbs.
You don’t have to fret about breaking the regulation if you use these steroids.
Anabolic steroids are schedule IV managed substances within the United States.
If you’re utilizing Winstrol for chopping purposes then lower doses tend
to be more effective (10-25mg); whereas if you’re
using it for bulking then higher doses are sometimes beneficial (30-50mg).
The outcomes you will notice (or not) from taking Winstrol rely upon quite a
lot of factors. Generally speaking, if you’re someone who’s seeking to maximize
the potential advantages of taking this steroid then it can take wherever between four to
six weeks; generally longer. On the other hand, Winstrol is a stronger steroid that can promote muscle
growth, albeit with extra severe opposed results.
Anavar (Oxandrolone) and Winstrol (Stanozolol) are oral steroids, and of
which Winstrol can be found in injectable form. Bodybuilders typically
have a hard time choosing between the two as a end result of they’re so similar.
To assist you to make your finest option for your self, we’ll evaluation the variations and key features of every.
We discover that if junk foods are consumed during a cycle, sodium ranges will rise, inflicting water retention. This can inhibit Anavar’s
diuretic results, inflicting the muscular tissues to seem more and more smooth and cut back muscle definition, striations, and
vascularity. When women take Anavar at 10 mg per day, we often see them expertise muscle features within the first 10 days.
A woman taking 10 mg of Anavar per day has a extra powerful impact than a person taking 20 mg of Anavar
per day. This is as a result of of males producing roughly 20x
more testosterone compared to ladies (30). Finasteride (Propecia) is an FDA-approved medicine
shown to be effective at blocking DHT ranges in the body
and decreasing hair loss (19).
In Distinction To the liver, these two cannot recuperate once they’re damaged, so you have to
use one thing to protect them. Similarities embody that both are dihydrogentestosterone derivatives,
that means neither will convert to Estrogen via the aromatase enzyme.
They will also be nice for pressure manufacturing, as
DHT has instantly been linked to energy.
Regardless Of this, stats have it that 54% of male
bodybuilders admitted regular steroid use, which is in all probability going nonetheless too low to represent top-level competitors.
Winstrol is also used by athletes who’re getting ready for a struggle or match of some kind, to enable them to build up
more strength whereas sustaining their weight.
Winstrol also helps athletes keep strength levels throughout
their off-season to permit them to begin with even larger strength ranges when the following season starts.
Due To This Fact, oral Winstrol is superior for quicker results,
which can be experienced in the first week of a cycle.
Girls shouldn’t go over 10 mg daily for greater than 6 weeks
to avoid virilization. Anavar and Winstrol both play a task in maintaining muscle mass, but they work in a
special way. This is beneficial for athletes who want strength with out
the extra bulk.
Count On an increase in energy and endurance, however the side effects
of Clen can harm your train ability (lowering the dose is ideal if
you’re delicate to stimulants). Anavar will present the capacity to build muscle
and maintain energy while dieting. On the draw back, Tren can negatively impact your
cardio efficiency and hamper your fat loss efforts. This stack will take dryness
and muscle hardness to a new level in comparability with Anavar alone.
However, more advanced users will go additional than this, using a number of different compounds at performance-enhancing
doses alongside Anavar. This is a helpful technique,
significantly for chopping and shredding (where Anavar excels).
Anvarol increases your phosphocreatine levels, which in turn helps
to regenerate ATP. This means more energy for intense exercises and sooner
gains in muscle mass. Utilizing a quantity of steroids on the
same time can increase the risk of antagonistic results and may trigger undesirable interactions between the
drugs. Over current years, Proviron has been used in bodybuilding and athletics as it’s believed to increase
the hardness of muscle tissue and cut back body fat.
In addition, Proviron has been shown to decrease estrogen ranges in the physique.
Estrogen is a female sex hormone that can promote the expansion of
breast tissue.
A common scam we see is for methandrostenolone (Dianabol) to switch
oxandrolone, as it’s cheaper to provide. This poses additional
risks for girls, as their chance of experiencing virilization is
excessive due to Dianabol. The fats loss experienced from an Anavar cycle may
also be maintained long term; nonetheless, a person ought to stay disciplined with their diet and training
if they wish to retain their results in the
future.
