I am back testing a multi currency EA. I noticed in my logs there are messages such as: 2015.04.23 19:00:17    Core 8    GBPCAD: history for 2015 year synchronized What exactly does history synchronization do? I see it

I understand that mt5 auto downloads history data when starting a back test but I was wondering if that is the data for all time frames or just the selected time frame? Would I need to run it on all time frames if I need the data from all time

Hello, Is it possible to code and back test an EA in mt5 that has 20+ currency pairs ? I do not want to test the currency pairs individually, I want to be able to optimize my indicator settings over all currency pairs at one time to achieve a

I noticed that when using indicators for back testing (e.g. cci overbought/sold) that results are completely different between brokers. What may seem like a good setup on one, is not on another. E.g. One broker shows the cci overbought but the other

This code works in back testing and most of the time forward testing but every now and then an extra trade will still be placed on the currency pair despite the check in the code below that SHOULD be preventing this. Trades do have different magic

I have downloaded hst data for required pair and imported it via the history center. It shows up there and I can backtest with it fine using every tick mdelling (verify this with visual mode). I know this is working as my broker does not supply the

I am back testing with Renko charts and although some pairs work just fine for some reason other pairs open one trade then immediately close it and does not trade any more after that. The error I get is: "tester cannot calculate prices". I do not

     if ( iCCI ( NULL , PERIOD_D1 , 14 , PRICE_OPEN , 1 ) > 100 ) Does this look correct? I have a feeling that the 100 will be referenced from the timeframe the EA is running on rather than d1

Hi, My EA always needs to check the last close trade but whenever mt4 is closed and restarted it does not read the last trade. Any ideas how I can code my EA to check the last trades result even when the terminal is restarted

Hello, I understand that mt5 uses broker server time when back testing but when using for example Alpari, this causes data to use daylight savings time whereas I need to test without any adjustments, ideally GMT for all of the data. Is this possible

Does the strategy tester have a limit on 10 currency pairs? When I attempt to run a test with anymore than 10 pairs it only loads the initial 10 pairs history before throwing errors such as: IJ    2  

Is this possible in mt4

I have read lots of information stating that back testing on generated offline renko charts is unreliable, however looking at the visual back tests it seems as though the tests are reliable when the EA does not use a fixed stop loss or take profit

Sorry basic question I know but wondered what is the difference between using || or &&? Example for each would be: if (OrderSymbol() == Symbol () && OrderMagicNumber() == OrderId2) if (OrderSymbol() == Symbol () || OrderMagicNumber()

I am backtesting my EA on the m5 and it uses bar O/C/L/H from a bar on a different timeframe (e.g. PERIOD_H1) and an indicator on a different timeframe. Now I would assume that if the EA is always using the PERIOD_H1 timeframe and indicator values

Am I the only one having an issue with launching the mt4 build 600 terminal? I have installed multiple instances on my VPS yesterday and launched with no problems but trying to add a few more today and after install the terminal does not launch

I am trying to print the times to my chart but the format is not correct: Log: 2014.02.04 17:47:29.079 Expert Time Check EURUSD H1: Local Time Is.1391536049 GMT Time Is.1391536049 Current Time Is.1391543240 Code:       

Is there any way I can prevent this from happening or to send the order again if it fails? My EA can place multiple trades and I am not sure if this is causing the issue, the fact I have 10+ terminals running or just poor EA coding on my part. The EA

Can someone please tell me what the UTC/GMT offset of the data in the history center of MT4 is when testing at the moment

I am using dukascopy data and getting 99% modelling quality on the m1 (not sure that is even possible) and when I click open chart, the entries are not even within the price of the bar, they can differ from the bars price range by around 20 pips
