bid(margin call) price is 269.74391
ask price is 265
it doesn't fill because the call price is greater than 265, for an example, it's 268.
if you want to fill it, you can give a bid order at price 265, this will fill the ask order.
then you give a ask order at price 269.74391(between 268 and 269.74391), this will fill the margin call order
I don't think you can know what the call price is(unless you own the order). As each order will have a different call price and it won't change.
Because the order is yellow and on the book you can assume the highest bid is less than than this orders call price.
The yellow order is the SQP price, or 10% below the feed.
So Flipping it over, lets look at the same order:
margin call price is somewhere above the highest BID of .00377
The ASK (SQP margin call order) is 10% below the feed or .0037 (yellow)
The highest bid is .00377 which is above the SQP and so the Margin Call should execute.
If the highest BID were higher, say .004 the yellow (SQP margin call order) would disappear off the book, if this BID were higher than the orders Call price, whatever it is.
Edit: I'm confusing myself here, so I may have something backward or wrong, but I think the above is right. I need to think of a better example maybe.
