EA THAT CAN LOOK AT BEAR CANDLE

Hi

I need an EA that can follow these steps

1) if I am on 4 hour timeframe ON HEIKINASHI, EA should see candle close of first change from bull to bear or vise versa....then (draw a line on normal candle close)

1b)  Look into lower time frame for entry (15 minutes, 5m 1m ) I should be able to choose which time frame to look at

2) Look at the last few  bear or bull candles ( or the lowest wicked bear candle)( I should be able to choose bear or bull in parameters) within the last 10-20 candles..see attached

3) Calculate the distance in pips of these bear/bull candles

4) enter a trade at  50% or 75% of the specific chosen bear or bull candle e.g bear candle 1 or bear candle 2(should be able to choose % to enter)

should have take profit, trailing stop, stop loss, timeframe, heikinashi and normal candle timeframe look up as my triggers

opportunity to add more stuff as work in progress
