How to apply a strategy to your chart.
can access the Inputs and change them if we like by right-clicking the chart and
selecting Format Strategies. A dialog similar to Figure 7.9 will open.
Another dialog will follow once you select Format (Figure 7.10.). Here you can
select any of the four input variables. Go ahead and select mmStop and change it
to 3000. Then click OK and then Close. That’s all there is to changing the inputs
from the user’s interface. You can always change them programmatically from the
EL Editor. The next line is where you must define any variables you may use later
in your code. If you have properly converted your trading idea into either a FC
or FSM diagram and then into pseudocode, then you will know ahead of time the
number and names of your variables. It doesn’t matter how well thought out your
pseudocode is; you will almost always come across the need for additional variables.
Don’t worry; you can always go back to the Vars or Inputs and add more variable
names. Here the only variable name that will be used is myBollingerB,anditwill
be initially set to zero.
