Need basic EA that opens/closes on alerts from indicator

Hi, I have an indicator which gives buy/sell arrows (based on close of candle), and I need an EA that opens a trade on the new candle, and closes on that same candle. I need the following parameters, with default values: Lot Size: 0.1 Max Spread: 2 Emergency Stop Loss: 20 Magic Number: 9014925 Sometimes, the indicator will give the alert a few seconds late, i.e. a few secs after opening of new candle, e.g. instead of 14:00:00 it will give alert at 14:00:6... so keep it safe, I also want another parameter: Max Delay Secs: 5 (so if indicator gives alert 5 seconds late, then EA does not trade). EA must be backtestable in MT4 of course. That's it, thanks.
