Candle Wick Price Movement Rejection: Support and Resistance For ThinkOrSwim

Candle Wick Price Movement Rejection

A novel method for finding hidden support and resistance

IDEA
When a candle opens, moves a great deal either higher or lower, and then returns to near the original position, it leaves a signifigant 'wick'. That rejection of price movement forms the basis for this indicator.

while doji candles are obvious to the eye, the rejections this indicator attempts to capture are less so. They are obviously more important on longer timeframes, but are also interesting to observe on shorter timeframes as well. See illustrations below.

SETTINGS
The indicator has only a single setting. The required ratio of this candle wick to the wicks of the previous 5 candles. Ratios of 3 to 6 seem to be good places to start. If you find too many levels to be useful, increase the ratio. Conversely, if you find it not showing you much you didn't already know, decrease the ratio.
