Hi all,

I noticed that the EA strategy tester (MQL5) Inputs tab lists the Stop Loss level and Take Profit level in points (see attached screenshot1.jpg file) but during testing I noticed that the calculations treat the value as pips, thus resulting in 10x difference in values considered. I am using a demo account that uses a broker with 5-digits in prices.  

Did anyone notice this before?

 

Many thanks,

Robert

It depends on the EA you're testing. You should ask author of the EA why it behaves like that.

Hi Alexey,

I actually found this on the EA generated by MetaEditor itself. This is what I did:

  • I selected New File, used the "Expert Advisor (generate)" option in the MQL5 Wizard
  • Selected the "Accelerator Oscilator" signal (but any standard signal will do the same - I tried few of them with the same result)
  • Selected "Trailing stop not used"
  • Selected "Trading with fixed trade volume"
  • and clicked "Finish" to generate the code.
In fact the comment with this information is generated by MetaEditor, this is shown on the code snippet below:

 

//--- inputs for main signal
input int    Signal_ThresholdOpen =10;      // Signal threshold value to open [0...100]
input int    Signal_ThresholdClose=10;      // Signal threshold value to close [0...100]
input double Signal_PriceLevel    =0.0;     // Price level to execute a deal
input double Signal_StopLevel     =50.0;    // Stop Loss level (in points)
input double Signal_TakeLevel     =50.0;    // Take Profit level (in points)
input int    Signal_Expiration    =4;       // Expiration of pending orders (in bars)
input double Signal_AC_Weight     =1.0;     // Accelerator Oscillator Weight [0...1.0]

 

I also noticed that the SL calculation uses the function PriceLevelUnit() which returns 0.0001 for AUDUSD currency pair, thus indicating that the SL level is in PIPS. 

 Its not a big deal, but its a bit of a gotcha for people :-)

 

Many thanks,

Robert
