I still don't understand the collateral ratio. It makes no sense at all.

i.e. if I enter 6165.8 the TOTAL says 616,580.00 BTSX

wtf?

Short sell is still a sell!
As in you sell those $100 bitUSD and receive the BTSX proceeds from the sale.
so 200% from your account + 100% from the sale = 300% collateral.

Same explanation from a native speaker (BM) can be found here: https://bitsharestalk.org/index.php?topic=9289.msg120411#msg120411
Lack of arbitrage is the problem, isn't it. And this 'should' solves it.

You're also an accountant are you not? Of course you don't find it necessary, you deal with numbers all the time.

Is their a penalty for staying in a short position?  I thought I read something about that but I'm not sure.

The "total" is throwing me way off...

They should just make it so you enter 300% and bam it automagically calculates how much BTSX that is at that moment in time.

As a total, but

for 3X collateral you need to put

Short 100 bitUSD, with 3x collateral;feed of 30.829 BTSX/bitUSD

6165.8 =2* 30.8290*100 right now!

the 3082.9 BTSX will come from the sell of the bitUSD itself.

2* 30.8290*100

So I input 6165.8 into the text field?

If I leave the "price limit" field blank, my short will (dynamically?) execute at any price so long as it's at the price feed, no matter what that is?

I need more info on "collateral ratio". If I want to short 100 BitUSD into existence and back it with 3x the amount of BTSX, what should I input in the "collateral ratio" field?

2x the current feed price.

Do you mean 3x the current price feed?

i.e. 92.4 as of this moment in time.

EDIT: To clarify my confusion, I wasn't sure if I was to input collateral ratio as a grand total in BTSX (i.e. 9240), as a percent (i.e. 300%) or BTSX per BitUSD.

2x the current feed price * # of assets you are shorting
2x * 100 in this case.

2* 30.8290*100 right now! feed of 30.829 BTSX/bitUSD

BitAssets cannot be used as collateral *yet* but we are working on that.

The new rule are:
- shorts only execute at the feed price;
- shorts are ordered by the amount of collateral they are willing to provide ( i.e. >2x)
- short orders are now placed with min price they are willing to accept (in BTSX per shorted bitUSD)

If there is a feed even bitAssets can be shorted providing collateral in other bitAsset (do not take my word on this!!!)
