WHOM ARE YOU SCALPING?
No genuine broker minds you scalping the market.
A "broker" is someone who executes on his clients' behalf trades in an underlying market (in this case it's thew interbank market) to which the clients don't themselves have access. A broker isn't financially involved in the outcome of his clients' trades, and has absolutely nothing to lose at all, if the clients are successfully scalping the market.
(On the contrary, he likes it, because that's a good client who pays a lot of commissions and will stay there.)
No "counterparty market-maker", on the other hand (that's someone who's pretending to be a broker but actually holding the other side of his clients' positions and trading against them, while also holding the clients' funds and both making up and interpreting all the rules governing the transactions), will tolerate successful scalping indefinitely, because in this case it isn't the market that's being scalped: it's them.
It really is as simple as this.
