in 4º condition block, before BUY block. you have put (the low of candle).
in all condition block conected, ONLY OPEN A TRADE if all condition are simultaneously, there are a few conditions that the (the low of candle) is below MA, and close candle is up MA, and others conditions in same candle.

yes, it can.
the problem appears when i close and start MT4 platform, the Experts Advisors that was working good in offline charts, suddenly the robot remains off, and showing the STATUS of WAITING FOR TICK, and it does not work.
and MT4 show the error of: cannot set millisecond timer (1)

this is a code of fxdreema:

this appears in offline charts

maybe you have put the SL and TP very short, and when it open a trade immediately close and it open a new and it close immediately... as a bucle

I have an ea, built inside ON TICK, and in demo it sometimes I get this error (what appears in the error information console):
1 23: 05: 12.082 "My Expert" EURAUD, M2: cannot set millisecond timer (1)
and the robot remains off, and showing the STATUS of WAITING FOR TICK, and it does not work.

Can this error be suppressed by removing or changing any line of code within the EA?
