Potential sim usecases

[edd]

On Slack, I was asked what usecases I had in mind for the sim. I'm going to list them here. Some might not be appropriate. Some might be inappropriate. That's alright. Take what you want from this issue then close it!

Market configuration exploration

• Implement some bots that trade on a consistent known pattern. Then tweak market configuration to find out differently the network acts with changes to:
  • Price monitoring horizon
  • Price monitorring probability
  • Auction extension
  • Risk model
  • ...
• Then do the above but changing the market configuration via market update proposals

Network parameter exploration

• Where should we set market.liquidity.minimum.probabilityOfTrading.lpOrders? It's 0 on testnet.
• market.monitor.price.updateFrequency - it's 1s. Does changing it to multiple blocks affect trading much?
• market.value.windowLength ditto
• reward.staking.delegation.competitionLevel

Adversarial...ness

These are probably best tested with a full stack. But I was brainstorming, so here it is

• Can I spam x to [slow down/flood events] reasonably cheaply, even given the spam limits in place:
  • Amends
  • Pegged orders / pegged order updates

@edd The "adversarial" tests probably need to be done via capsule / full network.

Where null chain would come in is that we can develop the bots that give you the "market is still running fine" baseline behaviour that you try to disrupt. We'd need to complete https://github.com/vegaprotocol/vega-market-sim/issues/33 so that the same bots can be pointed at a running network / capsule.
