Hi there, I am trying to get in jforex code the value of the current color of any indicator using the chart.getIndicatorApperanceInfos()
and the method getOutputColors()
The indicator on the chart is SMA(21) and the setup of output colors are trend up = blue and trend down = red.
I am using the code provided by jforex wiki:

-----------------------------
For now I am printing only at the start to check the results.
but the code is printing the same color all the time, below the log:
13:29:13 testColor:java.awt.Color[r=64,g=64,b=255]
13:29:13 SMA Line last 3 values: [113.09614285714287, 113.07490476190478, 113.05504761904764]
13:16:49 testColor:java.awt.Color[r=64,g=64,b=255]
13:16:49 SMA Line last 3 values: [112.86409523809525, 112.86580952380953, 112.86761904761906]
Can anyone suggest the proper way to get that value ?
Or any other idea to get a flag to get informed every tick / bar when the indicator changes from uptrend to downtrend and downtrend to uptrend to trigger any action ??
