Buy/Sell News EA

Hi, i have a script to Open Buy and Sell Stop orders (which i will include9. I want to automate the process using variables like :

Date, Time (Local Time or ie GMT -5), % Risk, Stop Loss, Take Profit, Trailing Stop, Distance between price, slippage, Seconds to Open, Seconds to Close.

The ea will open both Buy Stop and Sell Stop pending orders with Stop Loss and Take Profit "X" seconds before the News. If one triggers, automatically close the opposite pending order. If none trigger after "Y" seconds close all pending orders.

The ea should be able to calculate the lots based on % Risk of Balance and the currency it is working on.
