Well here's a tip - if you want to use margin lending, DIVERSIFY a lot. Don't put more than 5% of your portfolio in any stock, particularly if there is even the remotest possibility that your margin lender will pull this stunt on you.
If you are diversified, a large fall in one stock or a sudden change in the rules by a margin lender is not going to cause you to be forced to sell out at the worst time.
