What exactly is the '4-hour range' used in this strategy?
The 4-hour range is the high and low of the first fully closed 4-hour candle of the trading day (set chart to New York time); you draw horizontal lines at that high and low and extend them for the day.
What confirms a valid scalp setup on the 5-minute chart?
A valid setup requires a 5-minute candle to fully close outside the 4-hour range (wicks don't count), then price must re-enter and close back inside the range within the same trading day before taking the trade.
Where should stop-loss and take-profit be placed?
Place stop-loss at the exact high (for shorts) or low (for longs) of the breakout candle; set take-profit at two times the stop-loss distance (2R).
