Here is a Straddle EA I made some time ago for SPOT FX.
I call it dagsEA_PendingPower and is best used if your trading around News events.
This EA will place a Buystop and SellStop Order x amount from current price, you can also set Stop Loss, Take Profit, and has Trailing Stop included.
Just click the Pending button and place the straddle pending Orders, once a pending order is hit and becomes an Open Order the other Pending Order will be cancelled.
There is a Close button that will cancel all Open and Pending Orders for that chart.
Please enjoy, dags.
