I think that when you risk your money and your real trading account, you are unlikely to forget about open trades that can bring you big losses when you forget about them. Therefore, I have not had such cases.
Then you are over sizing imo lol...half the time I have no idea where my portfolio is at because its a long term hold...much like somebody wouldn't have any idea what their home was worth at any given time. There are no big losses for me because I do not use stop losses.
That's a good sign. If you care about a trade then you need to size down. If you were trading with 100k account, and you had a $300 trade on...do you think you'd lose any sleep over it?
With a long term hold, yes, you can forget about your portfolio for a while)). I mostly day trade and don't carry trades over to the next day very often, so I don't have a problem with forgetting about my trades)).
I'm talking about day trading. I would trade 0-dte's from time to time, and after putting the trade on would go about my day, and see the outcome after market close...if you can't do that then you are over sizing...also if you are using stop losses you are over sizing. For example, had you bought 1k or 684 shares anywhere along the green line you would have been in profits like 60 times ranging from $100 to $1200 over the last 3 months. Let's split it down the middle as say you make $600. I doubt you could day trade this and make $600 over 3 months with fees and losses...and even if you could, you are working every day to accomplish the same thing doing nothing lol.
So tell us about your portfolio. Don't embarrass yourself with the dollar amount but let us know your recommended number of positions and how you suggest one manage a portfolio without stop losses. You know things like max position size, how much cash to set aside for averaging down, rebalancing and how and where to re-invest dividends. Again there's that credibility gap from an all in trader who runs out of capital and capitulates to the astute never take a loss long term hold investor. Dual personalities maybe???
