Modifying An Existing EA - modify money management

Hello,

I need to modify an existing EA in MT4 (MQL4) to have money management working properly with Futures, ETFs, CFDs and Stocks.

Current EA invests in a basket of assets (10 assets including Futures, ETFs, CFDs and Stocks) on a daily basis applying different strategies. EA invests every day at market open and divests at market closure(or when a take profit/stop loss is hit).

I need to modify money management, as I need to invest every day a percent of total equity in every asset and apply leverage, stop loss and take profit. For example for asset 1, 2,...,10 need to invest x% of current equity, with leverage x, stop loss x% and take profit x%. x are parameter to set.

I will share ex4 and mq4 files
