Hi, I am trying to write a strategy that uses the middle band of BB. The strategy builder has 2 x modes only for BB. The indicator in MT4 draws 3 BB lines. How do I refer to the middle part of BB for a condition using Molanis Thank You

In mt4 bollinger only has 2 lines that can be use in eas:upper and lower value

-Indicator line identifiers used in iBands(), iEnvelopes(), iEnvelopesOnArray(), iFractals() and iGator() indicators.
Constant Value Description
MODE_UPPER 1 Upper line.
MODE_LOWER 2 Lower line.

The 3rd line is a moving average. Just add a ma indicator with the same period and use that one.

Just used the MA and it follows the middle line of BB on the dot. Can move forward using this strategy now. Thank you

Please start a new thread and post your .moi file indicators. Also describe the issue in detail. It is really difficult to help if you only say it does not work - we need more info (what are you doing, what output you see, etc)
