Add a News Filter, Hedging Function to an Existing MT4 EA

I require a news filter added to an existing EA. This can use FFCAL. I would like the options in the EA inputs to set minutes before news and after news and have it not trade during news. Would like the options in the EA inputs for High, Medium, Low, and Speaks News so they can be set to true or false. Would also like the option for the EA to not trade on specific days, so that users can stop the EA any day, as in allow trading, Monday, Tuesday ETC. Would like a hedging option for when a trade is losing.
