Stock Market Days Up vs. Days Down Indicator for ThinkorSwim

[korygill]

Don't try to reverse engineer what this image shows...I'll post the code/description later...

Just wondering if anyone sees a way to play this indicator?

Well, not a lot of input here, but really I wrote this because someone said there are about the same number of up days and down days in a given year. So of course I set out to measure this...who knows, maybe mean reversion or something could be some odd indicator.

As promised, here is the code for this Up Down Ratio. The plots above are year/month/week on a 1-Day chart.

Enjoy

Well the obvious setup is 0 line cross on fastest momentum(bottom) when in confluence with slower momentum (mid).

Just play the center panel yellow/pink line

As a side note, I used to track number of down days and if we go to around 8-9 down days on the XAU, you could do a pretty low risk trade the next day was up. If it was not, double down. If not again, double down again. Kind of like the ultimate winning roulette strategy if you had infinite funds. /lol That said, there are better ways to play XAU then counting down days, but events outside the norm do mean revert, so it's not all that crazy. Check out my posts on FGMR for a working example of this in action.

Hi TOS experts,

I am trying to write a script that selects stocks that have 3 consecutive days of rising prices and with rising volume, once they cross SMA 20 for a specific market cap.

I have the preset market cap and SMA filters in the scanner.

How do i capture current close, previous-day close and previous-day-1 closing price and compare; and repeat the same for volume.
