If buying and shorting depth aren't deep enough, when margin orders are expiring, will they dump the price to 0? Maybe not likely to happen in the USD market, but in other market this might happen. For example in the current EUR/BTS market, 1050 EUR needs to be covered in 9 days, but the current short depth is only 1020. When those 1050 EUR are expiring, will they empty the buying order book? Does it mean that if I put an order right before those margin orders expire, e.g., to buy 1 million BTS for 0.01 EUR and I'll get the deal?
