In general if you use AFL to code stuff this overrides the Settings
values (not always)

Using the Settings values for Applystops is a great way to start.
If you want to use the above code in your backtester formula just try
something like this:

// Set all options here:
setoptions( 1 .........);
setoptions(2.........);
setoptions(3.........); //etcetera
BuyPrice = SellPrice = Open;// or whatever you want
SetTradeDelays(1,1,0,00; // etc.

// Define Buy and Sell conditions

Buy1 = myBuyCondition:
Sell = 0; // if you have only use Applystops to exit.

amount = IIF(Close < 10, ... , ... ); // etcetera
Applystop(stoptypeLoss,.........); // etcetera.

Equity(); // this helps to plot arrows on the charts so you can confirm
if AB is doing what you told it to do.
// if not you have goofed up code somewhere and

//then plot your stuff

Plot(c,"", 1, 64);
Plot(whatever else you want);
Plotshapes( ........); // etcetera

In general if you have got something wrong you will an error message
that will tell you how to fix this.
e.g, if you have not declared a variable first AB will object and let
you know.

so if you did
Applystop(StopTypeLoss, ......., amount,........);
amount = IIF( whatever........);

it will let you know with an appropriate error message.
