Yikes!
Conrad: Let me clarify...
Concept:
On Buys, PC increment = Trade $ amount.
On Sells, PC decrement = Cost of Shares sold (LIFO).
Example:
Last week I got a Sell on LAB.
I sold 500 @ 4.50 with proceeds of 2,250.00
The last shares I bought (Last In) were in October, 2010.
I bought 700 @ 3.30.
The Sell 'consumed' 500 of those 700 shares.
So the cost of the shares sold were 500 * 3.30 = 1,650.00
Therefore the PC decrement would be 1650, not 2250.
Again, I'm only pondering this approach in order to deal with adjusting any internals given Stop Loss actions.
