An EA based on KC Channel re-entry

Hi I need an EA based on Keltner Channel re-entry. 

The trading idea is based on a return to median line trade on shorter timeframe. The re-entry signal is defined by a close inside the KC after going outside. We place a Buy order at the high of signal bar (with buffer of 1 or 2 points) with the stop-loss at the low of signal bar + buffer. We exit the trade when the price reaches or cross the KC Median line.

I would prefer if you can also add algo optimization at 2 year period for the best profit factor with the following variables:

1. Timeframes (3, 5, 15)

2. Choice of trade based on risk/reward ratio 

If you can work on optimization, the idea is to optimize on a 2-year period and test on another 2-year period.

This trade idea is based on DJI Futures but am open to test on EURJPY or Gold.
