Like flags, pennants, channels, divergence's, wedges...things that people know already work?
No, these do not work over the long term. Eventually you hit a trade, or a series of trades, that blows out all of your gains and maybe more. Adding stop losses or profit targets does nothing for this, as it negatively adjusts your profits while trimming your losses. Those adjustments are zero sum. They may smooth your equity curve a bit, but if the curve is headed down, it's headed down.
You must remember that obvious things are not profitable in the long run. Many of the "simple" systems people push work well for long stretches, but give no indication when that stretch occurs, and have losing trades that kill the profitability of the system. These losing trades happen very infrequently, so to someone who does not thoroughly back-test, the system looks good. But they are just setting themselves (or their clients) up for a predictable fall.
Because these killing trades exist in the system, and the system traders don't know when they will surface, every losing trade ends up a possible system killer. You end up questioning the system, and not following the plan fully anyway. Though, because the system itself os bogus in the long run, the lack of following it is not the main problem here.
When you have done enough research, you will not fear your drawdowns. You will expect them. Following the system will be easy, and completely stress free.
