// When the ADX drops below threshold limit, then we consider the pair in consolidation. 
// Set Box around highs and lows of the last 20 candles. with upper and lower boundaries. 
// When price breaks outside of box, a trade is taken. (on close or on touch?)
// Stop is placed, default 50%, of the size of the box. So if box is 200 pips, stop is at 100 pips. 
// Profit target is 100% of the size of the box. Default. User can set a profit target of 0.5, 1 full size, 2 or 3.
