Title: Market history from blocks
Post by: csyk on March 23, 2018, 11:14:29 am

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

There is a `get_fill_order_history` API in history_api provided by the node, but I don't know what's the corresponding one in pybitshares (which is an API wrapper).

By the way, public API servers (e.g. OpenLedger) by default only stores history of 3 days. To get more data, you can run your own node with appropriate settings.

check out the Extinction Event framework, it allows you to backtest against centralized exchange data which should be sufficient for most altcoin/bitcoin pairs as:

LTC/BTC on CEX very closely matches OPEN.LTC/OPEN.BTC on DEX; at least on daily candle scale.

that's a crucial tidbit I didn't know
