To prevent collisions in static var names and allow you to run
multiple indicators simultaneously you must make the static var
unique by adding a prefix that is unique in each indicator. This is
what I started doing and it works fine. This is pretty safe since you
won't have the same indicator with the same release running at the
same time. If you want to use the same indicator for different
symbols you will have to add something to the prefix to make them
different. That could be the symbol name if your indicator is
handling multiple symbols. Anyway this will give you an idea how to
make the static vars unique.
_N(SectionName = "Trader Trends"); // indicator file name
_N(Ver = "Ver1_0"); // indicator version number
_SECTION_BEGIN(SectionName); // name of the indicator
// NOTE: VarPfx is used to make the static variables unique to
prevent bizarre results if you use multiple versions of the trading
program simultaneously.
VarPfx = SectionName + Ver; // static var prefix
// this is how you use it
staticvarset(VarPfx + "yourVarName", ...);
One thing to watch for. If you run trace more than one program can
dump trace data to the same file. That gets very confusing. Either
make sure only one is tracing or give each a unique prefix rather
than just using #.
Another thing. If you ever try to auto trade realize that only the
indicators that are visible will be active. The indicators on other
sheets you have will not be updated until you make them visible. SO
you can't use an indicator in the background to drive auto trading.
All the indicators you want to drive trading must be on the active
sheet.
