My suggestion to new traders: there are two important chart patterns to know: head and shoulder patterns (at the top and inverse head and shoulder patterns at the bottom), and rising wedges (at the top) and falling wedges (at the bottom).

If you see a head and shoulders pattern at the top, sell; if you see an inverse head and shoulders pattern at the bottom, buy. If you see a rising wedge at the top, sell; if you see a falling wedge at the bottom, buy.

You can backtest this. Remember to apply proper chart pattern recognition, and all rules of the pattern must be met.
