I got this indicator for mt4, I would like somebody to help me modify it so I can input an integer to select how many bars should be plotted. normally it will plot infinite bars, I'd like to be able to select the number of MTF bars the indicator should plot. This to eliminate the lag when changin timeframes, I imagine the lag is because of the big amount of MTF candles plotted.
Other change that I would really apreciate, if you see when open and close price is exactly the same it will not create a doji, it will only show wicks, not the classic horizontal line for a doji.
I paid a coder to make this, now he's chargin plus to make this changes, I tried to make them myself copying an indicator that has that function but my coding skills are hugely limited.
Thanks.
