Consecutive candle high or low indicator

The indicator should be able to identify consecutive high candles and consecutive low candles. The first candle must have a X pip long adjustable body for the first condition to be met, the candle must also be below or equal to the 20 stochastic level for consecutive high candles and above or equal to the 80 stochastic level for consecutive low candles. If the above conditions are met, then the indicator can look at candle 2. Candle 2 must also have a X pip long adjustable body for the condition to be met, however it is not dependent on the stochastic levels. Furthermore, Candle two should alert X number of seconds before the candle closes. Look at the attached image for an example.
