Backtest Arrows Not Showing?

[[Deleted]]

I am a developer, And I found this error :

1. When I use Bid, backtest don't show the arrow.

2. When I change Bid to Close[0], the indicator shows arrows properly.

What's the difference between them?

Shin Joo Young: What's the difference between them?	In MT4: Nothing (unless you're not returning from start/OnTick.) Your problem is elsewhere. In MT5: there is no such thing.
