Convert Strategy into a EA. Repost 2 - repost

I HAVE THIS STRATEGY FOR TRADING SIDEWAYS MARKETS AND ALSO USE PRICE ACTION. I WOULD LIKE TO CONVERT INTO A EA AND BE ABLE TO PROVIDE JUST VISUAL ALERT, ARROWS FOR UP OR DOWN SIGNAL WHEN AND ONLY THE RIGHT CONDITION AND MARKET TIME APPEARS SO I CAN MAKE MANUAL TRADE, JUST THAT, DON'T NEED TO PLACE ORDER, JUST SHOW VISUAL ALERT. ALSO PLEASE READ IT 2 OR 3 TIMES THE FILE SO YOU CAN BE FAMILIAR. I MARK WITH YELLOW IMPORTANT FACT OF THE STRATEGY. ALSO "I'M NOT SURE WHAT INDICATOR TO USE I'M NOT EXPERT IN THAT FIELD". ALSO IF POSSIBLE THE INDICATOR SHOULD NOT LAG AND NO REPAINT. THANKS, APPRECIATE YOUR RESPONSE.
