Fidelity doesn't show which sales are short vs which are long in the 1099 for me to know if the wash sales are disallowed just from short sales or not, but below is an example of what we see.
I trade every day multiple orders a day, in an out within minutes and sometimes seconds. never hold anything overnight. All with Margin. as you can see below, it shows realized gain/loss -147K, but loss disallowed is +138K - even when you add these up, the total is -9k - but I was net positive last year...
| Total Proceeds | 786,783,222.23 |
| Total Cost Basis | 786,930,372.97 |
| Total Wash Sales (loss disallowed) | 138,037.13 |
| Realized Gain/Loss | -147,150.74 |

| Box AShort-Term Realized Gain | 1,097,222.94 |
