I know most not into Scalping, but if one goes to higher timeframes, market principles never change. Markets have certain overall patterns in which one method works great at one time and not at other times like trendline Breakouts. When a market has normal trend and not a huge trend amount in one direction quickly, I will wait for a breakout, then wait for retracement to go into first direction. But on huge moves that go quickly, there are sideways patterns that can last several hours and just simple S/R entries with tight risk often are best trades. Trading Chop is my favorite way of trading. And Trading Trendline breakouts are different, I wait for the breakout and enter on way back. I find trendlines can hold so many touches and then it bound to break thru, but depending on what lead up to this point is more important to know whether to take or pass on the trade.
Nap time, am teaching my traders, so much harder than actual trading, LOL. Retired 2 days and already insanely bored.
