Pal, thanks, interesting calculations.  I assume you realize MFs trade
only at the close and "showing your hand" is not an issue.  The only
real issue is trading too frequently and getting penalized and/or banned
from trading the fund in the future.  I assume you know this.

Thanks again,

Ken

Assuming your usable_margin is the same as the total equity when you 
start your trading, ie., $50,000.00, the 

AVAILABLE_EQUITY(AE) = 0.1 * USABLE_MARGIN (UM);
available_equity  = 0.1 * 50000.00 = $5000.00;

If you determine your Max_System_%_DD or Max_Trade_%_DD using AB Back 
testing or MCS as 20% = 0.2

POSITION_SIZE (PS) = AE / MAX_DRAWDOWN_% = 0.1 * UM / 0.2 = 0.5 * UM

Position_Size = 0.1 * $50,000.00/0.2 = $25,000.00

If you want to trade 3 MF's, then you would invest $8,333.00 per MF.

Enter at opening range and/or at support/resistance depending on 
where the current price is at.  This automatically takes care of the 
volatility.  Mental Stops on day of trade at 1 full point away from 
entry.  Never reveal your positions.  Exit after 20 minutes only if 
your mental stop is hit and you are still losing.  Never show your 
stop on day of entry as this is equivalent to showing your hand in a 
poker game and the specialist's would view that with glee.  Use a 
3BSMA stop from next session onwards.

rgds, Pal
