Guys
Stupid question but I am trying to find when there is a buy or sell arrow using the RMO and am using the formula
Cross( Fml( "swingTrd 3") , Fml( "swingTrd 2"))
But I get allot of rubbish results. Once or twice the stocks selected have had an arrow but think that this is more good luck.
What am I doing wrong?
Thanks

Uncheck the "Load Minimum Records" and load at least 500 bars of data for the exploration.

Thanks mate, will try that this afternoon. 500 bars? seems allot of data but will give it a go.

FWIW, I often run 10-12 years, which is 2520-3024 bars/records.

I've said it before, I'll say it again... wabbit wrote:People often say "this doesn't work in the
explorer", or, "the explorer doesn't show the same results as the
chart". In about 99.99% of cases, this is because of the "load minimum
bars" feature or the user is being "lazy" and loading some insufficient
amount of data into the exploration (usually in an attempt to make the
exploration faster)
I put it to you; what would you prefer:
an exploration that is blindingly fast but returns the wrong results, or
an exploration that takes a little longer but returns accurate results?
PLEASE,
please do NOT ever use the "load minimum bars" feature of the
explorer. Force yourself to make a conscious decision about how much
data your exploration requires for accuracy EVERY time you run an
exploration. After all, SISO ([censored]in, [censored]out) and it's your money
that will be following the exploration down the drain! When using any exponential functions (infinite impulse return functions) you need to load AT LEAST 5 times the longest period of data, so in this instance you're taking a 30 period EMA of a 30 period EMA of 2 period EMAs, so load lots of data. I wouldn't start with anything less than 500 bars. If you're using any relatively modern computer, the speed difference between loading 500 bars in a simple exploration and loading 5000 bars in the same simple exploration is negligible. I ALWAYS load the maximum of 32767 bars, 50000 bars in system tests and 65500 bars on charts to ensure all computed indicators contain minimal errors. Time and well written code, I have; tolerance of errors, I don't have. wabbit [:D]
