scanning syntax errors inconsistent

earlberkun

I am developing a new scan and have 2 kinds of problems. Here is the basic scan:

[type is stock] and [sma(20,volume) > 100000]
//and [SCTR >yesterdays SCTR * 1.075]
rank by [PctChange(10, SCTR)]
//and [SCTR >yesterdays SCTR * 1.075]
#past 10 days ranked
//and [SCTR >yesterdays SCTR * 1.075]

Of the six lines, I can activate line 2 and get a correct message on the syntax. (Activate means erasing the //)
Lines 4 and 6 are copies (copy and paste) of line 2. When I activate either line 4 or 6, I get a syntax error. (Only 1 line of 2,4,6 is activated at a time)
Any ideas what's wrong? I've tried restarting Windows 10 several times. I've tried running this on a MAC. Same result.

The second issue is that when I run a scan in development, it's ok initially. When I add a new line to the existing 10 lines, all of a sudden it will not recognize the new line and scans for the previous criteria only.
Any ideas here?

Thanks for any suggestions.

There may be more than one problem, but the one that I see is that the "rank by" line is NOT the last line when you activate lines 4 and 6.

The "rank by" line must always be last.

Here's Chip's blog on the subject from a while ago:

and here's the link to the support page for "advanced scan syntax" which is VERY useful. They've done an excellent job updating the documentation. It's worth a look if you haven't been there recently:

I know it's hard to catch this stuff. If that is not the problem, let us know, maybe with a screen shot or quote of the error the engine gives you.
