EA to place BUY/SELL orders once price hits certain levels

Hi,

I would like to program a simple EA that can place pending BUY and SELL orders once the price hits certain levels. It should have the following parameters to be entered by the user. The BUY & SELL parameters should also be different. The pending orders shall remain until they are manually cancelled by the trader.

BUY

- Trigger price for BUY pending order: xx

- Price to BUY: xx

- Stop loss: xx

- Take profit : xx

 SELL

- Trigger price for SELL pending order: xx

- Price to SELL: xx

- Stop Loss: xx

- Take profit: xx

USDJPY Example:

I want to put a SELL pending order @ 123.398 with TP=123.150 & SL=123.810 when USDJPY hits 123.604. 

I want to put a BUY pending order @ 122.434 with TP=122.682 & SL=122.022 when USDJPY hits 122.228

Therefore, I shall enter the following values into the EA: 

SELL

- Trigger price for SELL pending order: 123.604

- Price to SELL: 123.398

- Stop Loss: 123.810

- Take profit: 123.150

 BUY

- Trigger price for BUY pending order: 122.228

- Price to BUY: 122.434

- Stop loss: 122.022

- Take profit : 122.682
