MAAngle Indicator & Averages

[[Deleted]]

I'm using this indicator to identify trends. I would like to use the values from multiple timeframes to give me a clear picture as to the short-term vs long-term positions. Getting the value is easy; the problem is that the min/max values are not fixed so the value could be bullish (green) on one chart and moderate (yellow) on another chart. Is there a way to determine the min/max value of the indicator or possibly the current color of the current bar?
