I don't fully get the wash sale thing to be honest
Isn't it something regarding taxes ? What happens if you sell and rebuy lower but you don't declare the "loss" because you lowered your position and you're okay with the L you ate to do so ?
Wash sales are all about taxes.
If you sell a losing stock, you can deduct the money that you lost on that stock from your other gains.
But, if you rebuy the same exact stock within 30 days, then its a "wash" sale and it interferes with your ability to deduct the previous losses from your gains.
So, its not that a wash sale is not allowed...it's just that it lowers the amount of money you can deduct from your taxes.
It might STILL be worth it, if you think that the profit you get from rebuying low will be worth more than what you lose from your deductions.
