I dont see any issue in todays market, from what I understand the broker combines the 0.01 orders and submits them as one bigger order to the banks that require a minimum of 10,000

Real ECN/STP Brokers Wtih 0.01 Lot = Myth or Reality?

Kinda makes sense to me, if the broker is offering dma execution. Why would the banks be happy to cover the millions of negative balances for trades? If its $50, then I cant see the broker chasing it

Brokers chasing you for negative account balance
