Hi Jeanlouie,
Picked up something here in this indie :
Whenever I choose to load on box for a 24hr cycle, and I choose US open time for start and 23h55 min later for close, the box shift in height whenever I switch between M and M5 TFs.
Any other TF is fine.
This only happens in this instance.
a single 24 hr box for asia, or london, or three boxes loaded with each session's own start & end times, no issues of boxes " jumping in height values" between any Tfs
What i found experimenting, any 24hr cycle , 00h00 to 23h55 , 10h00 to 09h55 up to 14h00 to 13h55 works fine, 15h00 to 14h55 up to 21h00 to 20h55 starts to give different box positions M1/M5 TF switch.
This is on a broker GMT+2 MT4
Hope you can fix this
