Humble Student OB/OS Trifecta indicator

After reading Cam Hui's blog post about his "Trifecta" bottom spotting model I thought I'd try my hand at scripting it as an indicator. The results are pretty close to what he describes. Though the data TradingView feeds me doesn't seem to be identical to what he's using on the results are close enough that I will call the effort a success worth publishing.
