It's cool. We only have to write the OnDeinit() function. In the OnDeinit() function will hold the cleaning schedule. Homework: write code to delete objects by prefix.

Help: ObjectsDeleteAll.

Vladimir Karputov 2015.11.09 13:36 #18

Check the folder "Projects" in MetaEditor.

P.S. For optimization it is necessary to limit the number of bars to draw the arrows.

But it won't be today.

Attach version "1.04" file.

Forum on trading, automated trading systems and testing trading strategies

please help me to put buy and sell arrow on this code.

Karputov Vladimir, 2015.11.09 13:36

Check the folder "Projects" in MetaEditor.

P.S. For optimization it is necessary to limit the number of bars to draw the arrows.

But it won't be today.

Attach version "1.04" file.
