Hi Toofuzzy,
Zero cash in the machine, the cash is in a central cash reserve. If you have a buy, import the cash into the machine and do the buy. The central cash reserve is shared by all machines. It makes the spreadsheet a bit easier for me and cash is not linked to a particular machine. I know when a machine has used a lot of cash, the buys get exponential in that case, time for a Bear Buy or a super Bear buy as Jeff Weber is doing. There are other ways to limit the use of cash.
Zero real shares, there are virtual shares ( you can also start with some real shares).
If you have a sale then sell the virtual shares or exercise a Vealie. I would like to have zero real shares with a machine that is going down or starting to go down.
When I am not sure about a stock I like to start with zero (or not too many) real shares
Best,K
