Quote from steve46:
Loosenup:
If we are talking about derivatives, the trader is subject to exposure limits. He/she gets a daily sheet that maps out exposure. and lists inventory. This is your "book". The general program is written and/or developed by the quant (the guy with the Phd) then the traders execute within the limits of the program. "Within the limits" means that they try to keep exposure to the greeks (delta/vega for instance) within a certain allowable boundaries. At the end of the day, your positions are reviewed by your manager and you had better be within limits. Losses are expected periodically. At the end of the year the bonus is calc'd from the bottom line. Hope this helps. Steve46
steve46,
Thanks. So, you are saying traders in big firms are actually only executing a predetermined program written by quants? Can you tell me a little bit about what these programs try to achieve? Do they mostly try to capture arbitrage opportunities by exploiting pricing differences across all kinds of derivatives? Do so called traders in big firms employ technical analysis at all? If they just follow the given quant programs, is it fair to say that traders in big firms are really not required to be good traders? Rather, they must be good program follower, maybe try to execute better to save a bit of slippage and execution costs.
Thanks a lot.
