EA sell/buy trades based on reversal indicator

Looking for a buy and sell indicator Arrows should be placed at closing of candle for confirmation and then not disappear or repaint. I am looking for a serious devleper who doesn't play games waste time and knows what he's doing so I can build a long-time professional relationship with him. I would only be willing to put the deposite down after I know it doesn't repaint because many developers pulled me to arbitration over the indicator that I found out repainted.   I don't have a strategy I expect the developer to come up with it. The image I'm adding is for reference as it's probably impossible to achieve that level of accuracy consistently but please don't be am idiot and try and sell me something that clearly isn't profitable in the long term.
