Cash management,
Cash management for AIM machines is for me not the same for each machine.
Existing ETF machines have their own cash level. Shares are bought and sold and the cash level goes up and down. Cash is allocated to each machine.
In my UBA I can't buy new shares, so I receive the dividends and export the cash from the UBA machines and the cash typically goes into 'free cash'. I made a few changes to the spreadsheet for this. Once a week I look at the 'free cash' level.
In the 'individual share' machines I had cash allocated to each machine. However I liked the UBA cash management and started using that: import cash when a machine flashes a buy and export cash when a machine flashes a sell or received a dividend. This simplifies things, the cash level is always zero. Of course you need to have enough cash in the 'central cash facility'.
Also the environment of individual shares is more dynamic, you sell a stock completely or buy a new stock. It is now maybe a good time to start an AIM-zero machine (a virtual machine with no stock, and the buys are real buys). Having cash at zero level in the machine makes management a bit easier for me. So that is why I calculate cost (what did I pay for the shares) and market(what can I get for the shares).
