Hi Joe,
thnx.
what problem i am facing is that while the writeif signal is coming
wrong; for the same indicator if i output the variable value directly
in exploration window it comes correctly. the colour change also is
coming right for few indicators and failing for some indicators.

BarCount does not represent number of bars in the DATABASE,
but in the ARRAYs in current execution.
The arrays have DYNAMIC size depending on zoom factor. That's why BarCount may
and will vary.
For example if you have 20 years of data and you are watching just
the last year

day no matter where you set the date range; and I get buys and sells on t

Hi Kim --
Yes, I agree that it is necessary to be able to understand, modify, and

Thanks for your quick help Tomasz. So, BarCount represents the last N
bars, where N simply varies depending on the zoom factor.

I'm a bit confused by your EnterTrade call. You have the last
parameter set to one, which is the position size variable. If the
price is more than one and PosSize is only one, then that would only
allow a fraction of a share to be purchased.
