It is specified at "1.66 New features" that
Option history files in .t8 format are now automatically loaded by contractUpdate.
While the contractUpdate() description specifies that "normally ask-bid prices are loaded for contracts with existing open positions".
How does it actually work?

If you have open positions, the prices of the related contracts are automatically updated in live trading. In the backtest the contract prices are known anyway, since you normally paid for them.
