For those that scale in/out , imagine your trading edge slowly diminishing because your well capitalized broker has been following your trades. We need a privacy law enacted for trades.
But say a big trader wants to submit 10 market orders of 100 each. Is it front running if the broker places a trade for his POA clients after the 1st 100 but before the 9 other orders for 100. Or say the broker places a trade after the 5th order for 100 but before the other 5 orders.
brokers are totally not interested in what the clients are trading
unless the client is a very special client with good track record.
do note most clients lose money and definitely brokers wouldn't want
to look at their trades. Brokers don't want their minds
to be contaminated by looking at those lousy trades.
Commission is zero. How do they make money then?Of course it is front running and the broker is shady, agreed. I would stay away from such outlets. Brokers should be in the business of generating commissions not trading pnl.

The way this game works.
After a big winning run there tend to be losing periods.
Your account will get noticed during the winning streak.
By the time they start copying your trades your account will soon enter the losing streak. And they will lose money.
And some point they will throw in the towel. Just before your next run starts and they will miss the winning trades.
I wouldn't be surprised if IBKR does this shady practice even if they charge commissions for trades. Almost everything in their backend is automated.
Your tinfoil hat lead you to move from a shady broker with sub 20 accounts to interactive Brokers? You do realize they have entire compliance departments and are audited and have to adhere to strict regulation and guidelines. Each and every account transaction is logged and tracked, even those by employees or in employees PA accounts. Your suggestion is ludicrous.

, not to mention taking the other side of the Auto Liquidator
