Issue of submitting multiple orders repeatedly in IOC mode #130

Closed 0xdaduck closed 1 month ago

0xdaduck commented 3 months ago

When testing my strategy, I found that there was an error in submitting multiple orders when opening a position. When printing the order details, I found that exch_timestamp was always 0. Is this a bug, or is there a problem with my data? In addition, I want to know whether the time unit in ConstantLatency is nanoseconds or something else? I am using the rust version 0.3.2.

Please see the document. NoPartialFillExchange and PartialFillExchange The supported order types and time-in-force options vary depending on the exchange model. IOC and FOK are only supported in the PartialFillExchange.

However, liquidity-taking orders may show greater discrepancies, as they have a higher chance of causing market impact, which isn't modeled and is very difficult to simulate accurately in the backtester.
