Yeah, it's called "learn the game", i.e. the language :)


Well I remember that the principle is based on the fact that there were times of 1min. and then to see a period of 20min. data are taken just by 20 bars for 1 minute....

the point is...then I didn't think twice about it...))

 

People! Look at the MA trend change, can anyone help? https://www.mql5.com/ru/forum/131277/page159

 
If it is not difficult to advise which period should be set for Murray levels so it does not lie or for each TF its period. If it has its own period then which ones?
 

Good afternoon!!!!!

Can you tell me where is the mistake...... when compiling no errors, but does not trade in the tester's log eSvechi+MA AUDUSD,H1: OrderSend error 131 and what is the reason - I do not understand

ERR_INVALID_TRADE_VOLUME 131 Incorrect volume, error in the volume granulation. You need to stop all trading attempts and change the program logic.

The logic seems to be correct.............................................

Good afternoon!!!!!

Can you tell me where is the mistake...... when compiling no errors, but does not trade in the tester's log eSvechi+MA AUDUSD,H1: OrderSend error 131 and what is the reason - I do not understand

ERR_INVALID_TRADE_VOLUME 131 Incorrect volume, error in the volume granulation. You need to stop all trading attempts and change the program logic.

The logic seems to be correct.............................................


Lots should not be less than (+ sort of multiple of) MarketInfo(Symbol(), MODE_MINLOT);

Many traders' programs have 0.1, but yours is 10 times less.

 
ilunga:


Lots must be at least (+ sort of a multiple of) MarketInfo(Symbol(), MODE_MINLOT);

Many traders' programs have 0.1, while you have 10 times less.

AND ALL !!!! The whole catch is this!!!!!!!!! .......... Well what about small depots of 5 -10 bucks???????

changed lot to 0.1 still does not trade
 
igrok2008:
changed my lot to 0.1 still not working


ran on InterBank, everything works even with 0.01

Alpari at 0.01 gives error 131, at 0.1 it works
