Just playing around with some ideas this morning and thought I'd try HA candles on multiple timeframes, and trading based on first candle reversal. In other words, buy at close of first green after series of reds (as close to closing price as possible, or lower), and sell on confirmation of first red daily candle.
Downside risk exists, but stops will pull you out of the trade, so a hedge is recommended. Can play with multiple timeframes and size appropriately to your risk profile.
This produced approximately 550 points in this period of time.
The idea works great, espeically on trending markets. I agree that the big winners should outgross the small losses by a good margin, even on shorter time frames like 5 and 30 minutes.
