Custom Indicator

This Indicator Is a Custom Indicator with Sierra Charts, I found another trader using it, This is how he uses it.
I use the macd/heinken indicator. it measures strength and direction longs are done when indicator is going up and we get a pullback and heiken gives red dot while candle is blue opposite for shorts
In the process of examining a system someone sent me I attempted to look at the indicators being used and see if they would be of any value for what I am doing now. they weren't then I thought lets see what happens since I am using a 13 tick range bar chart if I put a 13 sma on an see if any more trades could be added via pullbacks to it and what do you know it does. so here are the simple rules in a down trend when price pulls back an you you get a green dot and a down candle that's the trigger bar once it breaks put limit 2 ticks above low opposite for longs. now usually I was just looking at the strength indicator and waiting for it to slope and get them which I will still do but with the sma when price comes back to it and we get the green dot down candle we can take those too

Sadly its not available in MT4.
I am hoping that some of the great programmers on this site may be help, I see this as a very usefull Indicator, a new approach to divergence.
