TTM scalper indicator Backtest

TTM scalper indicator of John Carter’s Scalper Buys and Sells. The methodology
is a close approximation of the one described in his book Mastering the Trade.
The book is highly recommended. Note the squares are not real-time but will
show up once the third bar has confirmed a reversal.
