Hi Toof, Thanks for sharing. It's probably OK to split an AIM into two accounts, though it makes things a bit more complex. When I've done that I added two columns to my spreadsheet to keep track of the shares in each account. There's an issue if one account is much bigger than the other, then when you get a trade, say a sell, you have to sell a smaller number of shares from the small account and a larger number from the large account; otherwise the large sell will overwhelm the smaller account.
IMO it's best to avoid such splits as it makes the process more complicated and difficult. In a smaller account it's best to limit the number of stocks/ETFs and not share the AIM machine with a large account. The trades should be proportional to the size of the account and yet not be too small to keep the algorithm efficient.
