Simple Expert Scalper M1-M15

Hello, I would like the help of someone here to make a scalping expert advisor. The advisor should run on at least one of the following timeframes (preferably all of them): M1, M5, M15. I would like the advisor to look for candle patterns/situations where there is a high probability of predicting the correct direction of the next candle, it should then use a grid-like system to place multiple stop entry orders all along the next candle. Trades shouldn't last more than a candle or two maximum. There should be properties which can be configured for the grid size, the stop loss and take profit targets, as well as money/risk management and maximum allowed spread. The advisor does not have to make ludicrous profits in a short amount of time. I would like something that wins the majority of trades and is reliable in the long term. The frequency of the trading does not really matter. Once selected for the job, you should be able to provide me with a working demo before being paid. Thank you!
