Combo Backtest 123 Reversal & Fisher Transform Indicator This is combo strategies for get a cumulative signal. 
 First strategy
 This System was created from the Book "How I Tripled My Money In The 
 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 Slow Oscillator is lower than 50. 
 The strategy sells at market, if close price is lower than the previous close price 
 during 2 days and the meaning of 9-days Stochastic Fast Oscillator is higher than 50.
 Second strategy
 	Market prices do not have a Gaussian probability density function
 	as many traders think. Their probability curve is not bell-shaped.
 	But trader can create a nearly Gaussian PDF for prices by normalizing
 	them or creating a normalized indicator such as the relative strength
 	index and applying the Fisher transform. Such a transformed output 
 	creates the peak swings as relatively rare events.
 	Fisher transform formula is: y = 0.5 * ln ((1+x)/(1-x))
 	The sharp turning points of these peak swings clearly and unambiguously
 	identify price reversals in a timely manner.
