One has to go to each chart to change the parameters for that chart. The afl is a system so all parameters are needed so that Buy and Sell can be defined. I can, for example, change the Macd parameters via the top chart but these changes are not reflected in the middle Macd chart. I have to go to the middle chart, change the Macd parameters and then see the revised Macd chart.
I really can not put parameters within each 'if' as I need for the system buys and sells. I guess I will have to live with this. Thanks for the help as understand another way of doing charts. --- In [email protected], Keith McCombs <kmcco...@...> wrote: > > Bistrader -- > I rarely use Param() -- > However, I _believe_ that if the Param() statements are outside and > before the plot() statements that they will effect the three charts > equally.
