Able to set max simultaneous trade #1053

Open HardenedSteel opened 4 months ago

HardenedSteel commented 4 months ago

A market maker should able limit how many maximum trade opened at same time. With this feature possible malicious arbitrator could rug less coins.

woodser commented 4 months ago

Offers are intentionally funded and verified so multiple offers cannot be created with the same funds.

HardenedSteel commented 4 months ago

I think you misunderstand me, This feature will limit amount of opened trades at same time. For an example if the user sets the limit 1 then if someone takes an offer from that user rest of the offers will be disabled.

As I stated above this will limit the trust to arbitrators.

woodser commented 4 months ago

The intention is that all offers on the books are fully funded, and won't disappear when some offers are taken.

HardenedSteel commented 4 months ago

this issue is for making it disappear in order to limit the trust to arbitrators.

woodser commented 4 months ago

It would enable a fractional reserve, where people can post offers to sell xmr they don't have.

HardenedSteel commented 4 months ago

that's the case with #1055 this issue is different. The limit is about how many trades are opened, not how much XMR is traded.

woodser commented 4 months ago

Ah I see, so a user could post 20 offers, but only be able to have 5 trades active at a time for example.

HardenedSteel commented 4 months ago

yes correct, the idea is minimizing the risk by not putting the all funds in once

boldsuck commented 4 months ago

You can enable or disable individual or all offers in 'MY OPEN OFFERS'. I can post 20 offers, but only be able to have 5 trades active. I do this with instant trades, for example. I disable them and leave all the others activated when I go to sleep.

I like this idea. Example: I make 20 offers, all funded. I have max-open-trades set to 5. In retos case there are currently 2 arbs, if one goes rogue, they on average get 2.5 offers assigned to them instead of 10. Sure, they could quickly close out their 2.5 offers and start new ones, but now they only get an average 1.5 assigned to them and 0.75 on the next round. Eventually, all 5 max-open-trades would be assigned to the non-rogue arbitrator and the rogue one couldn't get any new offers from me. Once there are more arbitrators, this effect becomes even greater.
