I have a question for those amongst us that understand indicator code (I'm not too good at this yet) in order to access indicators in a strategy.

A nice example is the attached MASlopeBoxMulti indicator, which can display the slope of any of a good selection of moving average indicators.

My question is: how can the slope that is displayed on the chart be used as an entry or exit trigger in a strategy? How can we code for this in a strategy?

Cheers,

In your .zip, a DataSeries is used to store the slope, but it's not always needed.
You can just use a variable, which stores the current slope, computed using the 3 previous values of the "thing" you want to apply/compute the slope.
For example, the slope of a EMA(20), in degrees:

 

Code

//init private int _ema20slope ; ... // OnBarUpdate() _ema20slope = (int)(180/Math.PI*(Math.Atan((EMA(20)[0]-(EMA(20)[1]+EMA(20)[2])/2)/1.5/TickSize))); if (_ema20slope > 45) { golong();} if (_ema20slope < -45) { goshort();}

Sam, I'm seriously impressed. Thank you. I'll have a go.
