Basket trading EA with initial trailing stop loss and user input direction

I am looking to have the following trading strategy written into code:-

the first trade opened in any direction operates as a stand alone trade with a trailing stop loss. The first trade opened must adhere to the user input Trend. i.e. If the trend is Bullish then the first trade opened must be a buy and sell signals are ignored. If that trade becomes a losing trade and a second trade is opened in the same direction then the trailing stop loss is no longer valid and the two open trades become part of a basket. Same goes if a 3^rd and 4^th etc trades are opened in the same direction. There will then be and overall profit target according to the user input (TakeProfit) of all the combined trades in that direction. Once the initial trade is opened and becomes a losing trade then hedging trades are allowed as long as the price is above(for a sell) or below(for a buy) the initial trade and the signal conditions are met. This trade can operate as a stand alone trade with a trailing stop loss until it either becomes a losing trade and a basket trade is opened . Each time a basket trade in a specific direction is opened the lotsize is increased by the Smartinggale amount from the user input. 0 means the lot size remains the same as the original lot size
