Time Machine and back/lay amounts available.

I really like the Time Machine function, but have a question regarding how reflective of real life it is with regard to the amount of money available for a given market when backtesting strategies. Does Time Machine have any record of the money that was available for backing/laying in any given market/game, or does it simply assume that a request to back or lay will be met? (i.e. any value, however high, could be specified for a back or lay amount, and it will automatically be met with Time Machine, even though in real life for the selected historic markets/games, the amount required wasn't necessarily available.)

No, unfortunately we don't record amounts and they are fake when you play.
