I'll say again that % loss is mostly under your control. Barring a significant gap up/down against you, you can close the position at any time. Given the big leverage of spreads, I can't see any reason personally to allow a 50% loss (by which I assume you mean 50% of the max loss, not 50% relative to premium gained). I'm not sure there is a perfectly absolute rule though like "always close at 100% loss (relative to premium)" but something along those lines is I believe likely much better than getting in a position where you either are forced to take a huge leveraged loss or find yourself having to tie up capital rolling positions for little to no gain and hoping to get out. You can always re-open positions, and if the stock moves hard and fast against you you will get an even better position.
You are correct - that was a 50% of max loss for the position (actually had 3 of them in different accounts, that went for 40-70%), not of the premium received.
Stuff I learned:
- you are absolutely correct; I do have a lot of control over how much loss (%) that I take. I was pretty new to spreads at that point and I made the mistake of taking too big of a position with too small of a spread, not enough knowledge, and not enough smaller positions to start gaining that knowledge and experience.
- I didn't have as clear of an understanding of just how much I have control I have over the loss. BTW - Even with our relatively small steady weekly gains, I bias towards being ready to take larger % losses to give positions time to run and be rolled / managed. If I'm netting 2% / week and take the occasional 20% loss then I'm still ahead each quarter (not as much as I'd like, but still good by any other standard). 20% realized p/l losses are really rare - like 2 this year rare and I'm getting a lot better about lowering even from there.
- early days for me on spreads - I had WAY too narrow of a spread for how close to the money I chose my short call to be. Like $20 wide spread ($$ $$ dancing in my eyes) and the share price went through the midpoint so fast my head was still starting to spin. So I went with the 'take the loss' management choice when it turns out a 1 week roll for time would have been a max win (frequently the case; it's the infrequent cases that can wipe you out though depending on position sizes and management).
Closest to ADVICE I have based on my own learning - establish a small spread position that is hyper aggressive and designed to go ITM and need to be managed. With shares around 1170 that might be an 1150 put (start at least a bit OTM so you see the share price moving into your position and gain that experience also). One might do a range of different spread sizes - pair that 1150 up with an 1130, an 1100, a 1050, a 950, whatever width spreads that sound good to you. One of each of them maybe. Or some small very total position size that is big enough to keep your attention, and small enough that if they all turn into max losses it won't matter.
You may find that you need to run these aggressive spreads for a few weeks or more to have them go ITM. That'll be fun (high % gains), and should not turn into an effort to make more by making the positions bigger - the purpose is education and experience in a controlled sandbox type of circumstance, not the rate of return.
I did something like this a year or so back where I took an ATM cc and kept running it ATM until it assigned (took a few tries). I was consciously and intentionally running the wheel, including going through assignment each way. The Wheel strategy has always been one of my backups / management choices, and I learned that I was fine with shares to cash (put assignment), but did not like the cash to shares assignment (call assignment). What I didn't like was being out of shares and into cash, as I was constantly worried about the shares taking off and me not being ready. The emotional side of that particular strategy didn't work for me, which made it much less likely that I'll ever do that again
