Trading with Market Statistics. IV Standard Deviation

Recommended Posts

Soultrader,

 

I used to track POC but I find that particularly for the S&P's, the VWAP is the key level to think about. the concepts are similar though.

 

I have spent a lot of time trying to fit PVP into something useful for me but I just don't think it adds much to my set-ups so I am not using this. my advice would be to start with just watching VWAP and learn to see how price reacts to it. there is a ton of good information by watching how it responds to a test of VWAP or a break away from VWAP. I find it fascinating to watch the action the S&Ps have relative to VWAP.

 

the one set-up that is very useful is that when PVP = VWAP in the middle of the day, think of it state of near-perfect 'balance'.

 

other than that, I only look at PVP in context of overall profile shape.

 

here are some notes from todays action.

This unfortunately is a misleading statement.

Near perfect balance would be price = PVP = VWAP.

 

Very often when PVP=VWAP, price action can be far from the PVP, even as far as the 3rd Standard Deviation. That's not a balanced market.

Hi Jerry,

 

I am still a little confused on what VWAP, SD, and PVP you use. Is the PVP the previous day PVP? Or do you use the current day's PVP. Also is this also the case with the VWAP and SD?

 

If applying historical data in combination with todays VWAP, SD.... is this 2 days back? Or do you use a continous VWAP and SD for the entire contracts lifetime?

I think I can answer that and I am sure I will be corrected if wrong but for everything except position trading (the very last thread) the developing profile for today is used. So basically you have nothing until the first tick at 9.30.

 

In the series on scalping Jerry suggests a way for jumping right in if you are keen for action!

 

Cheers,

 

P.S. are you in China yet Jerry? Hope you are enjoying yourself where ever you are.

pretty clear that the vast majority of what jerry has written about has used current days pvp, vwap, sd.

 

so at the beginning of the day, you have an especially undeveloped data set. after that, the data set will gradually mature to the point where VWAP esentially gets to where its going - as incremental volume becomes less and less important to the VWAP calculation as the day goes on since you are building a larger and larger volume base on the past (ie, VWAP will change a fair bit from 10am to 1pm but will not change so much from 2pm on unless you are in a very, very strong trend). the idea is that it is profitable to make trades looking for statistical extensions/retracements based on the current data set -- while fully realizing that the data set is dynamic and will very often have different statistical characteristics as the day goes on.

Thanks Blowfish,

 

This will indicate that a trader using this methodology must wait until the VWAP, SD, and PVP becomes clear? The SD usually takes all morning before widening up for the Nikkei. This is why I was thinking of applying this technique for the afternoon only.

 

However, I am trying to figure out a way to play the open. For example, if price is below the previous day VWAP and PVP go short, etc.... Im curious to here any comments on such strategy. Perhaps add a few filters like candle patterns, etc...

<<For example, if price is below the previous day VWAP and PVP go short, etc....>>

 

no idea how the nikkei trades but if it is the first down day after a series of up days, then I like this thinking. if price is below the previous day vwap but the last few days have all seen lower and lower VWAPs -- then price might be expected to start low (morning low) and trade to an afternoon high in a reversal day.

 

but in general, VWAP > VWAP[1] or VWAP < VWAP[1] is an important thing to monitor, in my opinion. if 'building higher value' --- look to go long after a downswing completes and vice versa... this can really keep you from fighting the markets theme for that particular day.

Thanks Dogpile, Im actually going to look into this behavior and jot down some notes and ideas on it.

 

I have another question regarding the SD. How narrow is narrow? It appears that Jerry would take trades with risk:reward ratios of slightly below 1.0. I personally do not take these type of trades even if Im scalping. If scalping the minimum I aim for is a 1:1.5 risk reward ratio. I understand that these risk:reward thinking is not entirely correct as it is geared for newer traders. However, I just never found myself worth taking a trade with so little reward opportunities.

<<I have another question regarding the SD. How narrow is narrow?>>

 

I will let jerry answer that particular question since I don't use SD at all -- but here is a comment.

 

I use a set number of points from VWAP as kind of a ballpark number to consider -- and try to think more in terms of strength (momentum/volume) of that particular move more than anything purely statistical based on historical data. The market is dynamic and while statistics are crucial to understand -- I don't want to get TOO caught up in statistics as I think there are better ways to do it. but to each his own. jerry very likely has a ton of nuances to his approach such that when I see some of his trades --- I find that we are actually often making very similar trades -- but we are getting there in totally different ways. thus, jerry has figured out through experience how to get a ton of information looking purely at the statistical distribution -- stuff that I just can't see when looking only at a distribution of prices.

 

I know some traders where some combination of oscillators just speaks to them and I just don't get how they do it -- but they do. this is kind of how I think of jerrys approach. he is pulling more out of it then I can certainly see. he has likely been able to do this because he has learned all these little nuances that go along to his approach. kind of like in poker -- there are all those situations that you have seen many times if you have played a lot of hands but each particular situation is actually a very rare thing --- so you get good once you have seen enough hands to build up a library of all those rare but cumulatively important situations -- that is the difference between profit and loss.

Both Blowfish and Dogpile have correctly stated when to use today's distribution and when to use yesterdays.

Since today's distribution has not developed yet at the open, use yesterdays distribution and simply add on to it as the morning price/volume data develops. I do this for position trades as described in [thread=2423]part X[/thread]. You can then switch to today's distribution at your convenience.

I understand that these risk:reward thinking is not entirely correct as it is geared for newer traders. However, I just never found myself worth taking a trade with so little reward opportunities.

 

To restate this question, how large does the SD have to be before you enter a trade?

If you are only using today's distribution, then at the open, the SD is virtually zero. As more price/volume data is added, the SD grows. What's nice about watching this is you can see how the volatility is changing as the day continues. First growing, possibly leveling off, then growing again, then reaching some kind of stasis.

So when should you first consider taking a trade? My rule of thumb is, don't trade until the range of the bars on your chart are less than 1 standard deviation. If the high of a bar touches 1 SD level and the low of the bar touches a second SD level, then the bar range is too large to consider entering a trade on that time frame. You either need to wait until the bar range gets smaller, or go to a faster time frame.

Can somebody please advise me on this code.

I am a newbie to Easylanguage.

I am using this code on mullticharts

Comments appreciated

 

Naveen

 

 

vars: vwap(0),

pv(0),

Totalvolume(0),

Barfromstart(0),

Squareddeviations(0),

Probabilityweighteddeviations(0),

deviationsum(0),

standarddeviation(0);

If date > date[1]

then

begin

Barfromstart=0;

pv=AvgPrice*volume;

Totalvolume=volume;

vwap=pv/totalvolume;

end

else

begin

Barfromstart=Barfromstart[1]+1;

pv=pv[1] + AvgPrice*Volume;

Totalvolume=Totalvolume[1] + Volume;

vwap=pv/Totalvolume;

end;

deviationsum=0;

for value1= 0 to Barfromstart

begin

Squareddeviations=Square(vwap-avgprice[value1]);

Probabilityweighteddeviations=volume[value1]*Squareddeviations/Totalvolume;

deviationsum=deviationsum+Probabilityweighteddeviations;

end;

 

standarddeviation=SquareRoot(deviationsum);

plot1(vwap);

plot2(vwap+standarddeviation);

plot3(vwap+2*standarddeviation);

plot4(vwap-standarddeviation);

plot5(vwap-2*standarddeviation);

 

 

Hi,

that code works properly for me, I see we are all worried about VWAP to be plotted in Tradestation; but my real concern is how to plot PVP, if I use AVGprice function I never have "round" prices to work on so how can I say what price showed the maximum volume in the day?

Bye

hi, check out the thread in Trading Indicators. Blowfish looks like he should have everything pretty much nailed down at some point as far as matching Jerry's videos.

Thanks for the suggestion, unfortunately I did not get the PVP code there, furthermore other codes I found are ELD format and using Prosuite 2000i I cannot read them, please see this attachment and maybe someone can read it and post it here in order for me to "transport" it into prosuite 2000i.

Thanks, bye

Howard Arrington just told me he is including SD as a built in study in ensign to be released today in the nov 8th beta.

 

Looking forward to seeing this.

 

In his words.....

 

"VWAP with standard dev band based on price-VWAP is now a built in study in the 11-08 beta to be released later today.

Enjoy. You can do away with the DYO for VWAP now."

Would it not make more sense to convert the VWAP bands into an oscillator. Here is essentially what it would look like:

 

http://www.charthub.com/images/2007/11/09/VWAP_Oscillator.png

 

This way, you have one histogram, instead of 5, 7, 9 lines overlaying your candles. The histogram tells you how many standard deviations price is above or below the VWAP. I'll add this oscillator option to our next release (I/RT 9.0).

That's fine for the forward candles, (the ones all the way to the right). However the oscillator gives the wrong impression about where price has been relative to the standard deviations in the past, due to the fact that the standard deviation lines are renormalizing with each added data point.

For example from 12:20 to 12:50, the lows of all the candles touched the 3rd standard deviation price which kept renormalizing to a lower price.

The oscillator on the other hand gives the impression that none of those candles touched the 3rd standard deviation until about 12:40

Hi Soultrader,

 

I used to use several current day volume based studies on the Nikkei but found that the opening print often ends up distorting the information for most of the morning as you have commented on above. I ended up changing the studies to tick based or time based. Maybe take a look at those for alternatives.

 

My best regards,

MK

Interesting you should say that MK. I have recently adjusted my Volume bars to self-scale for the last 20 bars but I exclude the opening bar and, for SPI, include all bars after the close of the cash market. This makes Wyckoff style volume use much more effective.

 

How are things going? (pm me :))

Hi.

 

Sorry to bump this old thread but I've been reading this entire series of threads and am trying to follow along.

 

I'm using SierraChart and have loaded the VWAP but I can't figure out how to get the SDs loaded. When I add the SD study and base it off of VWAP, I get new lines that are very close to the VWAP. I've attached a pic to show what I'm talking about.

 

My options for the SD study are:

Top Band Input Data

Bottom Band Input Data

Length

Multiplication Factor

Moving Average Type

 

Any ideas on how to correctly set this (or code my own SD formula is this one is wrong) are appreciated. Thanks!

The default multiplication factor is 1.8, which is what was used in my screenshot above.

 

When I calculate the SD of the VWAP manually I get values like .05. Hardly useful when the YM moves in 1 point increments.

The problem is that in fact you don't want to calculate SD of the VWAP itself. You want to calculate SD of VWP (Volume Wiighted Price, i.e. a price distribution where probability of each price is defined by volume traded at that price). VWAP (Volume Wieghted Average Price) is the mean of such a distribution.

I don't use Sierra so I am unable to help you. But search Wikipedia for Standard Deviation, Variance and Mean.

    • Date: 29th March 2024. GBPUSD Analysis: The Pound Trades Higher But For How Long? The global Stocks Markets are closed due to Easter Friday (Good Friday). The NASDAQ continued to follow the sideways trend while other indices again rose. The SNP500 reaches an all-time high, but the NASDAQ remains under pressure from Tesla, Meta and Apple. The Euro continues to trade lower against all major currencies including the US Dollar, Euro and Japanese Yen. The British Pound is the best performing currency during this morning’s Asian session. However, investors are largely fixing their attention on this afternoon’s Core PCE Price Index. GBPUSD – The Pound Trades Higher but For How Long? The GBPUSD is slightly higher than the day’s open and is primary due to the Pound’s strong performance. At the moment, the British Pound is increasing in value against all major currencies. However, the US Dollar Index is also trading 0.10% higher and for this reason there is a slight conflict here. If investors wish to avoid this conflict, the EURUSD is a better option. This is because, the Euro depreciating against the whole currency market avoiding the “tug-of-war” scenario. The GBPUSD is trading slightly lower than the 2-month’s average price and is trading at 49.10 on the RSI. For this reason, the price of the exchange is at a “neutral” level and is signalling neither a buy nor a sell. The day’s price action and future signals are possibly likely to be triggered by this afternoon’s Core PCE Price Index. Analysts expect the Core PCE Price Index to read 0.3% which is slightly lower than the previous month but will result in the annual figure remaining at 2.85%. The PCE rate is different to the inflation rate and the Fed aims for a rate between 1.5% to 2.00%. Therefore, even if the annual rate remains at 2.85%, as analysts expect, it would be too high for the Fed. If the rate increases, even if only slightly, the US Dollar can again renew bullish momentum and the stock market can come under pressure. This includes the SNP500. Investors are focused on the publication of data on the UK’s gross domestic product (GDP) for the last quarter of 2023: the quarterly figures decreased by 0.3%, and 0.2% over the past 12-months. This confirms the state of a shallow recession and the need for stimulation. The data, combined with a cooling labor market and a steady decline in inflation, increase the likelihood that the Bank of England will soon begin interest rate cuts. In the latest meeting the Bank of England representatives did not see any members vote for a hike. USA500 – The SNP500 Rises to New Highs, But Cannot Hold Onto Gains! The price of the SNP500 rises to an all-time high, before correcting 0.33% and ending the day slightly lower than the open price. Nonetheless, the index performs better than the NASDAQ which came under pressure from Tesla, Meta and Apple which hold a higher weight compared to the SNP500. For the SNP500, these 3 stocks hold a weight of 9.25%, whereas the 3 stocks make up 14.63% of the NASDAQ. The SNP500 is also supported by ExxonMobil’s gains due to higher energy prices. The market will remain closed on Friday due to Easter. However, the market will reopen on Monday for the US and investors can expect high volatility. Investors will also need to take into consideration how the PCE Price Index and the changed value of the US Dollar is likely to affect the stock market next week.
