NEED SOMEONE TO HELD ADD SOME MODIFICATIONS TO MY CURRENT INDICATOR CODE AND TURN IT INTO A FULLY AUTOMATED EA.

I have an indicator strategy (with source code) that works pretty well.it works by sending notifications signals whenever either a buy or sell signal appears. It does so by drawing arrows in the chat (red downward arrow for sell and green upward arrow for buy). Now i would like to turn it into a fully automated EA so that instead of sending me notifications it can just open positions immediately whenever a given arrow appears. It should open an order when based on the appearance of the arrow only (because I decide when and where the arrow should appear) and should close either buy before or at the moment of opening a sell order. So, the code to add should take parameters from the arrows output. Also, I'd like to include a trailing stop-loss so that it can move the stop-loss along with the increasing profits. The order opened at once should take about 50% of the account balance. If you can please contact me so I can send you the specifications
