Allow trade to take profit and set stoploss by replying to the signal#634

Would be nice to have a feature where people can reply to the original signal message to: Update Stoploss price, Entry price, move stoploss to breakeven, and take profit by % at the current price

Example:
Move Stoploss/Entry to xxx price
Take 50% profit at current price
Take 50% profit and move Stoploss to entry price (Breakeven)
