MarketInfo not working on Strategy Tester [SOLVED]

New comment
 

Hello,


My EA is working fine on live testing on demo accounts, is opening closing and managing trades.

Most of the trades it opens has tp and sl based on the daily pips range.

I check the daily pips range with: 

Range = (NormalizeDouble((MarketInfo(NULL,MODE_HIGH) - MarketInfo(NULL,MODE_LOW)),4));

This works perfectly on live testing, but is always returning 0 on the strategy tester.

Any clue?

 
arimbur:
Range = (NormalizeDouble((MarketInfo(NULL,MODE_HIGH) - MarketInfo(NULL,MODE_LOW)),4));

  1. Be careful with NULL.

    1. On MT4, you can use NULL in place of _Symbol only in those calls that the documentation specially says you can. iHigh does, iCustom does, MarketInfo does not, OrderSend does not.
    2. Don't use NULL (except for pointers where you explicitly check for it.) Use _Symbol and _Period, that is minimalist as possible and more efficient.
    3. Zero is the same as PERIOD_CURRENT which means _Period. Don't hard code numbers.
    4. MT4: No need for a function call with iHigh(NULL,0,s) just use the predefined arrays, i.e. High[].

  2. Perhaps you should read the manual. In what calls are MODE_HIGH and MODE_LOW used? Series Array Identifiers - Indicator Constants - Constants, Enumerations and Structures - MQL4 Reference
