Quote from ang_99:
What is the s&p pit traders primary strategy? Do they still have an edge since its traded primarily electronic? Do they arb the difference in spread?
Anybody know?
It depends on the trader/s.
One strategy that they use daily is as follows:
Trader 1 on S&P Pit floor and Trader 2 outside on Electronic platform-both working for the same firm.
Trader 1 has a pager that sends him a "wake up" call when 10 min engulfment is forming on main S&P futures contract.
Trader 1 will go long on main S&P by "jumping the engulfment"-for this example we will keep it simple and say long 2 contracts.
Now we have Trader 2 enter the equation.
Trader 2 is watching the main S&P contract chart-not the E-mini which most follow-and when he gets the signal he will sell 5 E-mini contracts to offset 1 of the main S&P contracts that his "buddie" is long.
Trader 2 will then tighten the stop on the remaining 1 long S&P contract-by adjusting the sell stp lmt for the remaining 5 ES contracts- and when this is hit the 2 contracts have been closed out for a profit of anywhere between 1 and 5 points on the main S&P-not the E-mini.
They do this all day long on 10 min engulfment signals-and a few other techniques as well.
The average trader who is not aware of this strategy does not know how the markets operate-as they also use other techniques as well-which I will not mention for now.
When you look at the ES tape-look for multiples of 5-and you now know what is happening.
