YES! YES! Because in stock market, when I buy, the worse that can happens is the active fall 99% and I loose 99% of my capital. But, in sell position, the worse that can happens is the active grow up 1000%, or more, and I loose more than my invested capital! Because this, the sell positions are “short positions”.
Correct!?
So, in stock markets, the value of the active varies from zero to infinite, but, in currency markets, the value of an active can varies from 0.001 to 1,000, in exponential scale. This is the reason for my question: the concepts of short and long position should be applied in forex too?
Do you understand my question now?
Other thing, in this page ( Option (finance) - Wikipedia ) there is two types of buy and sell. Short Sell, Long Sell, Short Buy and Long buy. I read this article, but I didn’t understand anything. How can I understand what’s a short buy and long sell?
