To me it's not about whether Bill is profitable or not. He very well could be, don't know, don't care really (but would be interesting to see some live trades).
My concern is twofold,
1/the massive position size
2/massive contest risk
Lets look at the example several pages earlier where he purportedly trade 27 x 1000 share contracts = 27,000 shares of underlying, with a delta of approx 0.5 giving a total number of 13,500 deltas.
The bid ask spread is typically about 5 - 8 cents... lets say 5 cents to be generous.
That is 27,000 x $0.05 = $1,350
This means that if the share did not move and he exited, it would have resulted in a $1,350 loss PLUS commission.
It also means that the underlying has to move > 10 cents just to break even (remember our 0.5 delta)
That's a massive impost to overcome in a daytrading system.
Now compare that to Shares or CFDs where to gain the same 13500 deltas, we only need 13500 shares with a spread of typically 1 cent.
That's $135 plus commission contest risk.
The options are 10 TIMES more expensive to trade in terms of contest risk.
Daytrading sytems, if positively expectant :, are not greatly so, because you never get huge outliers.
They rely on trade frequency to make money.
Maybe Bill is a good enough trader to overcome 10x contest risk, maybe not, but are the people he teaches?
I would bet London to a brick and Mombasa to a melon that very very few can overcome this.
S you see it's not about Bill being profitable, it's about Bill teaching about the most inefficient day trading modality currently available... and charging money for it.
Thank you wayneL.
This has to be one of your best posts ever. Clearly setting out the structure, associated costs and risks of day trading options.
IMO not an arena for the beginner or those with a preference for low risk. One of the reasons I am happy to stick to trading shares.
