Well I´m not sure where I read that. But week before last, I was trying to close a calendar. The short side was either a couple of cents on a late Friday, or zero. I was trying to close the trade as a complete trade, using their list of trade types that places those orders. I spent a couple of hours trying to get a fill in TOS, but even though I would CANCEL the order and keep changing the spread, could not give it away, much less close it. Not knowing what to do, I let it expire. I simply ran out of time unable to get a fill on the trade. A week later I see I´m showing in TOS a QQQ order still open with a small profit. I call the HELP desk, by finger typing and they told me, because I had not closed the trade, I was forced to do it piecemeal, that that side was still open. It wasn´t stock, so I was not assigned stock. It was the indexs, which I did not understand and they did not explain very well. After some haggling, I just asked the guy to close whatever it was that was still open. Over a week later.
To make a long story short, I started reading up on assignment in indexes and there was something I read someplace that said they were assigning to stock, if you were doing stock, if it fell under .25 cents on an expiration Friday. In this case a weekly expiration. Then on one of these forums somebody else mentioned it, also. That you were vulnerable if doing spreads on stocks to be assigned the stock if you were under .25 cents on an expiration Friday. That you had to close on THURSDAY. So even though I am not at all clear on this way it works, I will close any such expiration Friday spread on late Thursday in future.
I suppose you could piecemeal the trade and sell the zero value side of whatever spread had a zero leg open. That might work? Thats all I know. I´m a novice and amateur so don´t know too much about such things.

The difference between paper trading when learning and then going to cash trading can bring up some quirks unexpectedly. Today Friday, I decided to place a real cash trade for a CALENDAR. To try it again. I wanted a short April Weekly and a long JULY. The TOS automatic listing for such things, I clicked on the CALENDAR, but it defaults to force you to take a weekly April and a LONG MAY. It has provision to change the long month to July. but the box for the spread value doesn´t change. AGAIN, I played with that for a while, but am very nervous, as I tend to forget their default is 10 contracts, when I only want two contracts. So after playing with it for awhile, and I was having trouble with my internet connection as well. I just gave it up in disgust. It was too late in the trading session in getting assistance from any of my friends on here and ask if I could leg into a CALENDAR, by going LONG JULY and then short the April as a follow up, seperately? That question is still open, if somebody would answer it? I may try again on Monday. In the meantime I simply wrote down the ask premium prices and did it on scratch paper as a trade. Figuring I would get some advice next Monday, perhaps from TOS, or some of my friends on here. I´m testing classical strategies trying to learn them.
I was trying to either get a cash money trade either in CALLS or in a STRANGLE, but the market would not agree on Friday afternoon, for July options. I ended up putting on a cash trade as a STRADDLE instead, for $2500, for 5 contracts. We shall see how that works out, as my chart reading shows we are not finished with downside pressure quite yet, but sideways pressure. Rather than lose the week by not being able to trade in the weekly, I chose to use next week to trade a STRADDLE instead. The other two weeks ago, I did that successfully and so fairly confident I can do it again. Rather than waste this coming week, because of market TIMING not agreeing with the strategy I was particularly willing to test in CASH money, instead of on paper. I´m just learning a lot of this stuff brand new. Between the TOS order platform and my ignorance I make the occasional mistake, which sometimes costs me a bit of money.
