I just draw support and resistance lines and use those. Combining breaks through the lines with particular sequences of bars or candles that have a high probability of a particular result is often enough to take profits.
I can track the movement either up or down just by drawing in extra lines that fan out from the starting point (either a high or a low that has been formed) and they usually tell me where the small reversals happen and the continuations happen.
Or, if the price starts to be in a channel, then just draw the channel in - it gives the entry and exit points quite well, And shows when a breakout from the channel occurs signalling a possible reversal in trend
Sometimes there is a curved shape that shows up and I just draw in a curved line. If the curve breaks it's usually followed by a strong move in the other direction...
Once a pattern is broken I just move on to the next. Very unsophisticated I know, but no less effective for it.
