How do I get reasonable parameters in AssetFix.csv for Stocks.

This is what I use for the AAPL - Stock
Price = 100
PIP= 0.01
PIPCost = 0.01
LotAmount = 100
Commission=0.0007
Slippage=0.02
Spread=0.02;



A typical trade looks like that:
[APPL::L7603] Sell 100@111.7550: +105$ at 21:00:00
Entr 110.6152 Exit 111.7550 Spr 0.0200 Slp -0.02$ Rol 0.00$ Com 7.00$

Is there a way to provide a fixed value for commissions?
Do my parameters make sense?
