Don't know PB, PR, or DP, but the other two
are:
fml(" ") is the value of the formula within the
quotes (another custom indicator)
int returns the integer part of a
number

Subject: [amibroker] Re: IIf
Function
Tomasz,Thank-you very much for the explaination.
What I ended up doing was going to the preferences area, plotted a 20ema,
and in a seperate chart plot 14 period adx. The theory is to go long when
adx is above 30 and the stock in question crosses the 20 period ema. Your
formula actual shows when they cross. I am also trying to import
some Metastock formula's. Does anybody know what FML, PB, PR, Int, DP
refer to? Thanks againJohn--- In amibroker@xxxx,
