This function checks to see whether the last "lookBack" bars when added together form a pin bar. If so it will return the high (for bullish patterns) or the low (for bearish patterns) of the pin bar - if no pin bar was formed a 0 will be returned. Parameters: + int per = period of price to obtain (eg. PERIOD_H4) + int lookBack = number of bars t…
