Hello, I am still looking for a solution to the below if anyone can help? The indicator is a colour change moving average so if the ma is higher than it was on the last candle then it will change colour to lime and down to red. I would like to introduce a "lookback" period to this so that it looks back 30 candles to decide whether it is higher or lower. This smooths out a lot of the brief colour changes. I think I can see the part of the code where it compares the last two candles but nothing I do to it will work, the ma's just disappear off the chart. I'm guessing that when I add the 30 lookback it is trying to look for data at the extreme left that doesn't exist. If that's the case then I need to start the indicator reference from something like rates_total - 30 but I'm struggling with it to be honest. Any help would be gratefully appreciated.

Showing color iMA using iCustom, is this the solution?

Indicator idea
The iMA (Moving Average, MA) indicator on the ' MA: trend N Bars ' segment will define the trend. DRAW_COLOR_LINE paints the indicator in three colors using the graphical plotting style. The first color - the trend is not defined, the second - the uptrend and the third - the downward trend.

The indicator allows you to more visually highlight trend areas.

Thank you, I've seen that one but I didn't like it as much.
