I’ve downloaded and successfuly run 99% variable spread testing, using your script to choose true (use variable spread). When I uploaded data I inserted 0.6 commission, no problem.

All works very well, thank you for the instruction.

My question is if I set set the use variable spread script to : false, what spread does it use ?

I assume setting it to false does fix the spread, and the tests shows a considerable better result, ie much easier to pass, NOT that I am looking for an easier test to pass. I am looking to compare a varaible spread test versus fixed spread.

Thanks, your insights/advice is greatly valued.

Cheers, Adam

Cheers…

Well, I am getting the same problem again
It’s weird….
Yesterday was working fine after repeating the CSv2FXT process for M30 and M1 TF….
Today I am getting 0 as the values for Ema’s indicators…so is not calculating values properly…
The code is Ok.
Any clue ? sorry to bother you about this…

Thanks !!

George

I repeated the CSV2FXT process for 1M and M30 timeframes and now is working fine. The code was ok.
Before I did it with the option to create multiple FXT files in a single run.
So something went wrong with that process… I guess.
Just to give you a feedback.

Thanks a lot.

Surely I have something wrong with my installation or my code. I will check.
Thanks for your time and your answer.
George

But my actual question: Do you still have an installer for the old MT4 version compatible with the patch? I messed around with my installation and end up with a fresh install to 413 so the patch doesnt work anymore as stated out.

Would appreciate a lil help

@ geroge:

i do multi TF backtesting with different indicators all the time.. no problems there check ur code!

greetings

These being said, I suggest doing some logging to check what’s wrong in your particular case because I’m 100% certain that EAs using indicators on multiple timeframes work fine in tick data backtesting. In fact, I’ve checked it yesterday for a TDS customer and if you don’t want to take my word for it, write the following in an EA and backtest it on two different timeframes on ~1 month of data:


int start()
{
if (iBars(Symbol(), PERIOD_M1) < 30) return (0);
static datetime lastM5bar;
if (lastM5bar != iTime(Symbol(), PERIOD_M5, 0)) {
lastM5bar = iTime(Symbol(), PERIOD_M5, 0);
double ima = iMA(Symbol(), PERIOD_M1, 30, 0, MODE_EMA, PRICE_WEIGHTED, 0);
Print(DoubleToStr(ima, 5));
}
return(0);
}


If you did everything right the results printed in the log should be identical. If they aren't, make sure that:

• The same CSV was used for generating the FXT/HST for both timeframes.
• The same GMT/DST settings were used.
• The files were copied to the correct location.

Thanks for your answer !

My EA works with 2 ema’s : one on the current timeframe (30M,1H) and the other ema with 1 Minute period. I run the EA in a MT4 normal strategy tester under 30M timeframe and it works fine. This means that the signal based on the 30M and 1 minute ema opens the orders correctly.

When I used the MT4 version with birt’s patch, it seems that the EA does not recognize the 1M ema indicator, since no orders are opened. If I delete the portion of the code corresponding to the 1M ema, the EA does open the orders. So we may conclude that the 1M period ema indicator is not recognized for any reason. If this is happening with other EA’s then this could cause misleading results.

I am using Oanda v. 401, dukascopy Jforex data and Birt’s patch version for r. 401. All HST files for each period are in the history/Oanda practice folder.

This is the portion of the code I have :

***** Current timefarme 30M EMA’s :
SlowMAbar0 = iMA(NULL,0,SlowMAPeriod,SlowMAShift,SlowMAMethod,SlowMAAplliedPrice,MASignalBar);
SlowMAbar1 = iMA(NULL,0,SlowMAPeriod,SlowMAShift,SlowMAMethod,SlowMAAplliedPrice,MASignalBar+1);
SlowMAbar2 = iMA(NULL,0,SlowMAPeriod,SlowMAShift,SlowMAMethod,SlowMAAplliedPrice,MASignalBar+2);

FastMAbar0 = iMA(NULL,0,FastMAPeriod,FastMAShift,FastMAMethod,FastMAAplliedPrice,MASignalBar);
FastMAbar1 = iMA(NULL,0,FastMAPeriod,FastMAShift,FastMAMethod,FastMAAplliedPrice,MASignalBar+1);
FastMAbar2 = iMA(NULL,0,FastMAPeriod,FastMAShift,FastMAMethod,FastMAAplliedPrice,MASignalBar+2);

RSIbar0 = iRSI(NULL,0,RSIPeriod,RSIAppliedPrice,RSISignalBar);
RSIbar1 = iRSI(NULL,0,RSIPeriod,RSIAppliedPrice,RSISignalBar+1);

****** 1 minute EMA:
MSlowMAbar0 = iMA(NULL,1,SlowMAPeriod,SlowMAShift,0,SlowMAAplliedPrice,MASignalBar);
MSlowMAbar1 = iMA(NULL,1,SlowMAPeriod,SlowMAShift,0,SlowMAAplliedPrice,MASignalBar+1);
MFastMAbar0 = iMA(NULL,1,FastMAPeriod,FastMAShift,FastMAMethod,FastMAAplliedPrice,MASignalBar);
MFastMAbar1 = iMA(NULL,1,FastMAPeriod,FastMAShift,FastMAMethod,FastMAAplliedPrice,MASignalBar+1);

if ((FastMAbar1 SlowMAbar0) || (FastMAbar2 SlowMAbar0)) //&& RSIbar1 = RSISignalLevel)
{
if (TradeNotPlacedYet())
{
if (MFastMAbar1 MSlowMAbar0)
{
OpenBuyOrder(); ****** NOT OPENING ORDER HERE, IF I DELETE THE if (MFastM… portion it does open the order correctly…
}
}
}
if ((FastMAbar1 > SlowMAbar1 && FastMAbar0 SlowMAbar2 && FastMAbar0 RSISignalLevel && RSIbar0 MSlowMAbar1 && MFastMAbar0 < MSlowMAbar0)
{
OpenSellOrder();
}
}
}
