Expert Adviser with a Trailing Sell/Buy Stop, Risk Management is Key not Trade Execution

My theory for this expert adviser is that any trade can be profitable with correct risk management and i believe the way to achieve this is fairly simple. Using a similar style to a martingale system where if the trade goes against our open position we open more trades to compensate and eventually close in profit. Except instead of these trades being executed at set point steps, we will use a trailing sell/buy stop to give completely variable trade gaps depending on market conditions.

The idea i have would be structured something like below, i am no coder, so this will need to be interpreted and adapted in the best way you see fit. This would need to work for buy and sell trades and also have adjustable parameters for initial trade entry points distance and expiry aswell as take profit and step for the sell/buy stop, maximum total trades and maximum pairs open at one time.
