Difference of Two Indicators?

[chinaexpert1a]

HI, has anyone done an indicator to plot the difference of two indicators? What I've seen so far is spread stuff, that takes two instruments, but I want to take the running difference between two indicators, for instance RSI(14) and another indicator of 14 period or something like that. Thanks!

Hello chinaexpert1a, thanks for your post.

That can be done like this:

public class TestRSI : Indicator
    {
        private SMA _SMA0;
        private RSI _RSI0;
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                //...
            }
            else if (State == State.Configure)
            {
            }
            else if(State == State.DataLoaded)
            {
                _SMA0 = SMA(14);
                _RSI0 = RSI(14, 3);
            }
        }

        protected override void OnBarUpdate()
        {
            var diff = _SMA0[0] - _RSI0[0];
            Print(diff);
        }
    }

Please let me know if I can assist any further.

Hi chinaexpert1a, thanks for your reply.

This would need to be developed as a custom indicator. I'm not aware of any existing indicator that will do this. The Spread indicator is the only similar one I know of.

Kind regards.
