Futures Market" by Ulf Jensen, Page 183. This is reverse type of strategies.
The strategy buys at market, if close price is higher than the previous close

during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.

Second strategy
The SMI Ergodic Indicator is the same as the True Strength Index (TSI) developed by
William Blau, except the SMI includes a signal line. The SMI uses double moving averages
of price minus previous price over 2 time frames. The signal line, which is an EMA of the
SMI, is plotted to help trigger trading signals. Adjustable guides are also given to fine
tune these signals. The user may change the input (close), method (EMA), period lengths
and guide values.
