Hi Guys,

I have a very straight forward code above. When I run in VISUAL mode, everything works perfectly fine.

BUT, in NON-VISUAL mode the x1,x2,y1,y2 are returned constants every time. Here is example of the output. 

NOTE: Others values got retrieved correctly as the candle pass.

leftPrice 1.12013 rightPrice 1.10816 time1 2023.07.24 18:00:00 time2 2023.07.19 21:00:00 x1 -1136 x2 -32 y1 -1 y2 -1 statusOne true statusTwo true error code 0

Please help, I have been stuck for days

Graphical Objects in Testing #

During testing/optimization graphical objects are not plotted. Thus, when referring to the properties of a created object during testing/optimization, an Expert Advisor will receive zero values.

This limitation does not apply to testing in visual mode.
