@miro1360 so helpful! I just have solved this problem.

@miro1360 I feel really confused, this ea works fine with out the top "block 263",but I also hope it can display last 300 bar's arrow , not only future, I want it when I just loaded the EA to display on the chart. thx

I get a huge problem by this EA, how it works on future and last 300 history bar when I just loaded it??? I feel really confused, can't find the right logic, Who can tell me the right block i should choose, thx very much!!
