Quote from gmst:
[Bespecially when traders are coming in with astonishing track records (let us say PF > 1.8 or Sharpe > 2 and 10 months positive out of 12). Imho, it makes complete sense for the firm to actually encourage such traders to increase their size from 40 contracts to more than 100 contracts (e.g. for ES which can take a lot of size). Agreed, such firms might then offer only 20-30% of the PnL to the trader and keep 70%. In spirit, this is the way locals used to back new people back in the day when most of the trading was in pits.
Traders with astonishing track records can trade their own money and make a fortune without any opm or partners, headaches or hassles, just as 99% of real professional traders are not involved in the trading education industry.
