Market Maker - no oracles available for DCR/LTC #2334

Open bochinchero opened 1 year ago

bochinchero commented 1 year ago

Fully aware that the MM bot is POC at this point, but I imagine this will be an issue on pretty much any market that doesn't already exist in a CEX. When the market doesn't have too much activity on the books (like DCR/LTC now) the basis price can drift significantly from where it should be (e.g. right now its 0.17 and in binance its ~0.20), oracles would really come in handy here.

Could this be calculated based on thbe USD or BTC prices of both assets on the pair?

Yes, if there is no oracle available, then the USD prices will be used to calculate a rate.

coingecko and probably other sources can give conversions for arbitrary pairs.
