Hi,

I working on a trading bot and I want to test my strategies on historic datas.
I am using pybitshares to communicate openledger blockchain, and I saw that there is no clue if an order is filled.
For example: https://cryptofresh.com/b/25477122 you can see that paying for an asset there is no blockhash only signed as virtual. How this transaction stored on blockchain and how can I get back the full market history from the very beginning?

Best regards,
Csyk
