I am using the Binance Mock Trading Futures exchange to test some custom algorithms before I deploy them live. However, the funding fee is capped at ±0.3 and so the price very loosely follows the Mark Price. For example, for the last day, it’s been $1k difference from Bitcoin’s price on all exchanges. For the last month, too, it’s been around $300-500 off the price.
I think this could easily be fixed by just giving it a wider range for the funding fee, to reflect the lower volume, or removing the cap entirely. That way it can behave more like the regular BTC futures exchange and provide a more meaningful testing ground for developers/users.
Thank you.
