Topic: Sometimes Live Volume for indicators are different between FST and MT4

Hi,

I have noticed this behavior a weak ago after resolving another issue here http://forexsb.com/forum/topic/4819/charts-are-wrong-for-fsb-vs-fst/
but couldnt find time to post a new thread until now.

I was able to recreate this behavior with 2 different machines, 3 MT4s with two different Demo Brokers and 1 Real account.

I used different Demo and Live strategies for it. For this example I have used standard Demo MACD Reversal.

My Setup (Windows 8.1 Pro x64):

1. MT4 with Armada Markets broker as a test
2. FST installed without any modifications (only selected multiple working copies)
3. Selected Demo MACD Reversal and simply execute it
4. Chart EURUSD 1 min

To recreate the problem I have simply wait 15 minutes and start comparing last loaded 15 bars.
Chances are you will get something like this (showed in my screenshot)

Let me know what you think or if I have done something wrong as this all are fresh copies of MT4 and FTS.

Thanks

Re: Sometimes Live Volume for indicators are different between FST and MT4

I'm not sure that the data in the MT4 History Center are same as in the charts.

Compare the volume from the MT4 chart with the data in the History Center.

FST takes data from the MT4 charts. MT4 also executes the trades taking into account the chart data.

Re: Sometimes Live Volume for indicators are different between FST and MT4

I see so technically speaking it is nearly impossible to get FSB = MT4 data, as History Center in MT4 will always load it is own data (it will be about 97~99% accurate to Live Chart MT4 data, with exception of Volume values as we can see in some scenarios).

You have a good suggestion. Is there a way for me to grab Live Chart data from MT4, as I am unfortunately not sure how to do it.

Thanks again.

It's very easy and it's my favorite method.

Press Ctrl + S on the chart and save the chart data.

You have to probable force MT4 to load more chart data by pressing Home key.
It becomes faster if you reduce the zoom to minimum.

Re: Sometimes Live Volume for indicators are different between FST and MT4

Hm interesting.

Please review screenshot. I have done exactly Ctrl+S method and exported live chart data from MT4 to desktop and picked one of the latest problem bars and seems like volume for this bar is 31 in Live MT4 chart as well as history center, and it is 27 volume for the same bar in FST.

I have attached a screenshot, let me know what you think.

Re: Sometimes Live Volume for indicators are different between FST and MT4

I'm surprised from that !?

I made a script to see what MT expert returns for that bar:

void OnStart()
{
   datetime totime = D'2014.06.09 19:58';
   
   string symbol = Symbol();
   string period = Period();
   
   int    shift = iBarShift(symbol, period,totime);
   
   int    digits = MarketInfo(symbol, MODE_DIGITS);
   string time   = TimeToStr(iTime(symbol, period, shift), TIME_DATE) + "|" +
                   TimeToStr(iTime(symbol, period, shift), TIME_SECONDS);
   string open   = DoubleToStr(iOpen (symbol, period, shift), digits);
   string high   = DoubleToStr(iHigh (symbol, period, shift), digits);
   string low    = DoubleToStr(iLow  (symbol, period, shift), digits);
   string close  = DoubleToStr(iClose(symbol, period, shift), digits);
   string volume = DoubleToStr(iVolume(symbol, period, shift), 0);
   
   Print(time + " " + open + " " + high + " " + low + " " + close + " " + volume);
}

The script is attached below. Run it on the chart and it will print the data in the "Experts" journal of MT4.
You can change the date in the script.

Thanks for script, modified and executed it successfully with latest example.

Maybe there is an issue with reading certain bars or refresh rate, but you understand the backend by far better so I can only guess.
