No he's correct, margin calls only happen once the call price goes below the feed price.
Then documentation should be corrected, because it says that margin call is triggered when the call price is between feed price and SQPP.
The documentation is a copy paste of a write up that I did before BM changed the mechanics to make it so that margin calls are only triggered when the call price goes below the feed price, there's a github issue for this in the graphene repo.
Call price is DEBT * MCR / COLLATERAL.
This is extremely confusing indeed ! If the documentation is not right on certain points, I really don't know where to go to find information to make myself able to take the right decisions.
I need to change this parameter (MSSR) as soon as possible. I don't want to have this market in a dangerous position in the next high volatility event.
Can you confirm a couple more think ? (and correct me if I'm wrong)
If I set the MSSR at 140% and keep the MCR at 175% :
1) The minimum collateral to borrow a BTWTY will be at 245% ( 140 * 175 ) ?
2) Is there a way to avoid asking for so much collateral ?
3) The margin call will be triggered at 175% of the price ?
4) I won't trigger any margin call by increasing the MSSR because they will be triggered at 175% of the price feed ?
5) Once someone has less than 175% collateral, he will be margin call and its order will sit at 140% of the price feed ?
6) The price at which the margin call order sit in the market move with the price feed ?
