Subject: [amibroker] Re: 'Simple!' dynamic applystop help please
Hello,
I was often dispointed with applystops, so i have written my own loop
to manage differents exits.
of course the code is a "little" long, but if you take some time to
try it you must find it usefull, below is an example to get two
differents profit, so you can change it to get two differents stoploss
