Looking to turn this Indi into an EA. EA enters trade when an opposing arrow is formed, red down arrow is a sell trade, green up arrow a buy trade. Stop loss is placed above/below recent high/low. EA will exit a trade when an opposing arrow is formed to that of the direction of the trade and trade in the opposite direction. Take Profits will be handled manually. Lot size will be equal to 1% of Equity/Stop loss pips. Please let me know if you need further information. MW.
