My primary method is to trade breakouts of resistance levels at the top of broad trading ranges.
I sometimes trade trendline breakouts, but I find them less reliable in my time frame. They seem to work better for short term moves. I am looking for big moves.
An exception will be if I see a stock begin to trend up and the 260-day moving average is also turning up. In this case I buy into the trend using my usual entry signals. The trendline is not part of my decision process and I in fact never draw trendlines on my charts. I do teach them though and sometimes write about them in Shares.
