This would end day-trading immediately.
But there is no will and no need to stop day-trading.
Actually there is. I signed up for a basketball sim, not a day-trading exercise. I am quite certain that in this respect I am in the vast majority. Good for the new rules.
And we don't need auto-bid.
I don't need auto-bid and you don't need auto-bid - but just imagine that you lived in Japan/New Zealand and that would change your mind.
Coming back to the day trading - If you think that this is purely a basketball sim, than you are wrong. Similar games are always to very large extend economical games. You cannot win only by using magic tactics - you have to earn money to afford good players.
I am not enthusiastic about day trading (you can check my transfer history) - but it needs to be allowed (and BB has even an achievement to earn in that matter). There is no will and need to stop/eradicate/remove day trading - there was a need to decrease it's profitability - now it's less profitable and that's ok.
