I need a robot to auto close my trade when price meet my specific criteria.

I am a MT4 user with my macbook in OS system, and i need a robot to help me check price and when it meet my criteria auto close my trade.

Description of the robot algorithm

 I am using the Heiken Ashi chart in my trading instead of the candle chart. ( same as the candle chart, the Heiken Ashi chart change colours while price go up and down. In my case, when price going up draw white bar, going down draw red bar.)

1. After I buy one currency pair, until the Heiken Ashi BAR changes colour close my trade.

FOR example, ( in H1 frame)

The MARKET WATCH IS : 1:10:00, I bought USDJPY, and the BAR colour IS white.  MARKET WATCH:2:00:01, it will draw a new bar,then if the previous BAR TURNED  to red, close my trade.

If the previous BAR is till white,keep going my trade.  MARKET WATCH:3:00:01, stars draw the third bar, if the second BAR is red close my trade, otherwise keep going.

2. When I sell one currency pair, same algorithm as  NO.1 until colour changes close my trade. 

I want it works for all time frames. 

Thank you so much if anyone can help me .
