This is a complete trading system which can be applied to a chart, backtested or used as an exploration for buy/sell signals.

It has backtested profitably on all markets I have tested it on.

Basically it looks for stocks that are trading in a reduced range compared to the previous period. For stocks that are trading at recent highs it will buy when the stock moves up within this range, it shorts when the stock moves lower within this range. For exits it either sells into increasing strength or if when the price pulls back (opposite for shorts).

When run as an exploration it will produce a -1 for short, 1 for buy, -99 for sell, 99 for cover and 0 for hold.
