It is not that you will receive better or worse quotes as that would be illegal - the quoted price is the same. The difference is that no one will bother with a 10 lot unless they get more edge or you get really lucky, which is why your order will end up in the book and eventually fills when a MM hits your order for lots more edge. If you raise your size to 100, someone may fill you, but it won't be at a better price than if it were a 10 lot or 2000 lot. BTW, 100 is small. The point is, if you send in small orders through a broker like IB, the smaller your size the more on mid or even the other side of mid you have to be to fill with a MM. When you are trading small size, it is sometimes other retail traders you are often trading with.Quote from FT79:
Could you give us more inside regarding trading SPX? I understand if you trade 10 lots or so the SPX is not market to trade but if I trade 100 per leg I'm an average SPX trader (the average contract per trade is around 90 for 2007). will I receive better quotes trading 200 or 300 lots per leg?
You answered your own question. Sometime, go down to the CBOE floor, stand next to the IWM/RUT/NDX pit [they are essentialy one pit] and then go to the S pit. It is not even close. The demand is so great for the S, the CBOE was going to swap the S into the OEX pit because the OEX pit is bigger and there is no one in there. For some reason, that was halted.Why don't IWM, RUT and NDX don't come near SPX? They don't have the liquidity as SPX but if you want market exposure for IT or Small Caps it's a great place to be. Sorry for all the questions but I'm curious about the statements you made.
