Hello experts,

I´ve been trying to develop my own expert but it is harder than I thought.

What I want is this:

I want the expert to calculate the average bar size of the last 15 periods, if the last bar is larger than the average and it is a bull bar then color it in blue, if it is a bear bar color it in red. The size of each bar is calculated measuring the high and the low of each bar, for instance, high: 1.2340 low: 1.2328, then the size of that bar would be 12 pips.

I believe programming this expert is easy, I am just not a good programmer.

Any help will be greatly appreciated.

Regards,

fx_trader

Average of (High - Low) == Average(High)-Average(Low)
Thus, we having this simple indicator:
