>>Is there a way of modifying the MACD Buy Signal explorer to only show those securities that have MACD cross over below the '0' line.

Add the condition: AND MACD()<0


>> If it can show the MACD cross-line in a deep slope down,

Not sure which line you mean here -- the MACD or the SignalLine?

And, don't you mean "steep slope up"? Which would have to be the case, if the MACD is crossing up over the Signal Line for a BUY signal?

Either way, you could use ROC to see how fast whichever line you're interested in is rising or falling.

>When you said use ROC, could you expand on the coding, please.

Code example: ROC(C,3,%)>0.1; Look up details in HELP (F1).


>Also, would it go into the filter as well?

If you want -- you're the one who thought it up! Use another AND statement with the rate of change function.

Suggestion: So you can visually see what you are creating/combining, add new Inner Windows and plot each element of your code into it's own window. Then, put the combined code into a Custom Indicator and drag that down into the main window, so you can see if it's doing what you want (in comparison to the separate "pieces".

Also: Look up the use of FML and FMLVAR in the manual or Help -- since you can call an indicator from an Exploration, it's better to keep only one version of your code -- this can prevent repeating mistakes in logic, typos, settings, etc.
