number of days a position has been held WATCHLIST COLUMN

[markallenwilson1016]

Does anyone have a code or link for a watchlist column that will calculate the number of days a position has been held?

Something like this might work:

def qty = GetQuantity();
def counter = if qty != 0 then counter[1] + 1 else 0;
plot open_position_duration = counter;

The reason I didn't use a sum() is that I only want to know the duration of the most recent open position, not some total of days in a position over the last year or whatever.

I don't use watch lists, so I'm not sure I remember how to make a column, but this should get you some of the way there.

I appreciate the reply and help. Tired the code but I could not figure out why it red flagged the first line. Understand you don't use watchlists, but any idea what the issue may be. Also, begs the question, what do you use to manage your potential trades, investments, etc.

I don't have any active positions these days that I manage... actively. When I did trade, I traded futures, and even then mostly /ES or /MES and /6E or /M6E. Occasionally others, but mostly those two. You don't need much of a watch list if you're just making trades on the same futures over and over. ;-)

As for why the red on the first line:

I hadn't realized that thinkScript Portfolio functions aren't always available. See this post:
https://usethinkscript.com/threads/...thinkorswim-are-now-working.18808/post-141972
for the sad realization that this has been an issue for a while.

Oh well.

happy trading,

@mashume While the results of some Portfolio functions may not be available you should never get a syntax error within a script due to unavailability... Your code should remain error-free and only a lack of results from a function call should occur...

 

[useThinkScript]

Portfolio functions are available in the watchlist

Go to customize
Scroll down to portfolio


Those are all that are available.

They are only available as watchlist columns.
ToS does not provide the ability to interact with them in a watchlist script
