How to place Symbol on top of previous candle high

New comment
 

How can we place a high in the previous candle high using code?

So I want to place an X or some character on top of the last highest candle from the past 10 candles.


Thanks!

search OBJ_TEXT and iBarShift on documentation

iBarshift is by time.

I would like to find the highest bar in the last 10 candles.

 
Use iHighest() and iHigh()

Impressive work friend!

One odd thing is it doesn't work when I switch charts.  

Also this is for mt5 I've got mt4. It worked once but not when I switched charts.
