Yes, you are right. In addition to the margin calls, there are also the stop losses. The only difference is that margin calls are hardwired and stop losses can be fine tuned to suit the different market environments.

appreciated this very much.

Question to example above.

Why margin calls and not just a bunch of stop losses?

Many long position with negative realized profit. Many shots are waiting were many stop losses are placed. A spike up in the stop loss area will trigger an avalanche of shorts.

Or are stop losses not powerful enough vs. margin call?

Many thanks for the insights provided with your blog. Don’t expect a “cascade” of followers, then this would be indicative your information being wrong (you know, the masses prefer wrong info). Instead, expect to have a few truly thankful followers.
The How To Trade section is awesome, keep doing it!

I follow your tweets with great interest. Both World and Scale.

Talking about real interest – Rome wasn’t built in a day.

Thanks for clarifying. Of course the underlying demand is (generally) not visible. I’ve only just started looking at Twitter but yes I think your comments on there are useful information. I hope that interest grows; although we traders are notoriously late adopters…
