Keith - thanks. I got a mess at this end with all of the variables and all. Need to print out, study and see if I can clean up. Is more time consuming and extensive (is that the word?) than I thought. At first, I thought, hey, I can just pass the final chart array item such as Macd histogram and Stochastic. Nope, can't do just this it appears. When I start over I will look at the action == for exploration and backtest. Thanks
