Don and Tom:

Since I don't use Newport anymore (it doesn't allow me to use a truly common Cash Reserve), I had to figure out how to calc the next GTC limit orders.

Staying true to AIM's general disregard for #'s of shares (it does all critical calcs in $), I simply use the following formulae:

Where:
- PC = Portfolio Control
- BR (SR) = Buy or Sell Resistance % Expressed as a decimal (Safe)
- BM (SM) = Buy or Sell Minimum
- SO = # of shares owned
- NBP (NSP) = Next Buy (Sell) Price

NBP = ((PC*(1-BR)-BM)/SO
NSP = ((PC*(1+SR)+SM)/SO

Buy order = BM/NBP
Sell order = SM/NSP
These last 2 are rounded to nearest whole shares.

I can certainly understand where one might want to do 100 share lots, but that's not practical if your AIM-ing VITR for example which has ranged from $20 - $105 since November of '99 (split adjusted). I have sold as few as 10 shares of this one using the formulae above.

Anyway, these are what I use. Any feedback would be appreciated.
