// Rob Reversal Strategy - Official
// Using Rob Reversal Indicator: Original
// Description
// This indicator is based on the strategy created by Trader Rob on the NQ 15m chart.
// 
// Timeframe for trading is 8:30am-1:15pm Central.
// 
// Above the EMA line, look for a long position. You will have a short candle, then a long candle that opens below the short candle. It will have a lower high and a lower low. Once the long candle closes, your entry will be 1 tick above the wick (green line) and stop loss will be at the bottom of the bottom wick (red line).
