Expert Advisor based on candle stick pattern and Zig-zag indicator

I want a trading robot that will be based on candle stick patterns and the principle behind Zigzag indicator(HH,LH,LL,HL), I will provide all details on a short video. I want a bot that can open either a buy or sell trade in 3 positions(Only opens a trade of the other position after closing the current position at that time)i.e it can not open a buy and sell at the same time or a buy and selling trade can not be running at the same time.

The bot should should have  editable parameters that includes a lot-size, buy/sell, number of trades to open, TP and SL for the different positions, Max Spread filter, Time and Date filter magic SL and TP level(i.e A level that when the price reach the bot will automatically close all positions)

The bot should also display on overall gain or lost pip counter on the chart. 

Should run on mt4/mt5

Should be able to backtest

I will provide more clarification if needed
