Interesting approach, tho. But don’t you think sticking to 15M timeframe might be a limit for swing traders? But I can see it is worth testing out for finding S&R
While many suggest drawing support and resistance based on simple tops and bottoms, a more accurate approach is to identify the most recent two green candles breaking a high for the top, and two red candles breaking a low for the bottom. This method works best on the 15-minute time frame.
