Zero commission will not help retail traders/investors in stocks/options. It didn't help retail investors/traders in retail forex and it wouldn't help retail investor/trader either in stocks/options trading. TRUST ME!! I traded forex before and the zero-commission totally fucked up my trading and caused me huge losses. I was losing big time until I was able to find a broker of what's called an "ECN broker" that charged commissions but at least sent your orders (some of your orders) to what's called "liquidity providers". Just ask anyone who's ever traded retail forex and ask them if they ever want to trade with a broker that charges no commissions. You have no idea how much you lost and are losing just for saving a few dollars on each trade. The "advantage" that @taowave is talking about that retail traders/investors might have is not in paying zero commissions. Don't be so naive. MM's would love for us to want to stay in the "zero commission" mode for them to reap all the benefits. This is the pitch "you are the one who's benefitting", "you have no cost"... that they use to convince us. Maybe you are a MM pretending to be a retail trader? LOL If @Darc can pretend to be a retail, why wouldn't you be a MM? LOL
So you are a pro, an institutional trader? Why are you trying to make yourself out to be retail to try to "listen to us"? And ask us questions like these: You should know since you are an institutional trader and should know whether they "buy and sell in chunks" (whatever it means)?
The zero commission caused you huge losses? Lmao if that ain't some Supreme level victimhood holy fuck man...
he's completely insufferable. see the other posts / debates re: infinite gamma, etc. great coffee reading.
You guys are definitely MM's. @taowave has at least admitted it. Advocating for non-PFOF means we would pay more commissions. WHY would we want to pay more in trading cost (supposedly) under the non-PFOF model especially if we are already losing in our trading? LOL Wouldn't we want to save more trading cost? Yeah you guys would be indeed fucked under non-PFOF because you guys are MM's and are reaping so much benefit under the PFOF model pretending to be offering savings in commissions to retail traders but extracting lot more when executing the trades.
