@brianluidog If the mempool is public, is it still frontrunning?

@0xfbifemboy probability q's felt fairly trainable. basically review first third of an intro to probability course and then work through a interview q list to familiarize yourself with the standard tricks. hardest part probably time pressure/problem solving

@sasuke___420 @dendisuhubdy Doesn't any exchange with a "buy now at this price" button outside of their lob need the exchange to act as an mm and take the other side of the trade?

@0x94305 So selling order flow in larger batches (PFOF, individual order auctions being the two extremes) yields greater "efficiency". But w/ batch size > 1 it's not required, or even clear how, to distrubute rebates/price improvement to users.

@0xfbifemboy and assuming equities/bonds market are efficient enough, you'd rather take the market impact

[David Zeng @dptowin]

@0xfbifemboy I think the difference is the price the Blackrock ETF vs the AMM trades at. If some asset increases from a to a' > a, when getting arbed, the AMM is selling at some price between a and a' while the Blackrock ETF gets to sell at (a' - market impact).

@S3archerAnon @0xdoug I remember seeing that I (and everyone else on Serum) was picking off Alameda's stale quotes on the SOL/USDC market. They were losing on average 1-2bps on their trades which I thought had to be intentional given how easy it was to quote profitably there...

@Alexwang212899 @awertheim busd/usdt both worked for me. their wallets are low on USDC right now
