Unsettled cash wrong calculated

[earth_imperator]

Today I did shortsell a Put (as CashSecuredPut) strike=4, premium=3.6,
and my "unsettled cash" went from $0 to $759.34 !
I don't grasp this. Shouldn't that not rather be just $360 ?
Asked the TD support, but so far no answer yet regarding this issue.
Anybody else had such an unexpected or illogical discrepancy?

Just a speculation:
I think the system maybe has a bug if one does the following:
Prior opening this position I had cancelled a not yet filled & unrelated GTC order to make funds available for this trade...

Just got this explanation:

I am not seeing a value of $759.34 showing on my end, but it looks like it is determined by the $4 strike price and the total proceeds of $359.34 from selling the option ($400 + $359.34 = $759.34).

I may be just too stupid to 'get it', but how on earth is someone paying you 3.6 for a strike that is only $4?

Is your vol at 500 or something?

It's a DITM strike for a spot of 0.3657 :

I love how a professional programmer assumes everything he doesn’t understand is a software bug.

he must write pretty shitty software to assume all software is so buggy.

On the flip-side, you don't want to blindly trust your broker's T5008s when filing your taxes. Most unseasoned 'traders' find this out the hard-way!

That's perfectly fair enough.... I'm a big advocate of double-checking results.

That said, prematurely jumping to the conclusion that there's a "bug" or you're right and they're wrong is not a great character trait. This is @earth_imperator's modus operandi.

Digging deep, doing your homework and making good judgement calls in these matters is critically important.
