Firstly making money in the market is about riding on a major trend. Why are people buying stocks as the market drops? It is because they wish to ride on the next bull trend. So if you don't wish to trade during a bull run, just close your eyes and open them a few years  to see the value of the stock.

So what is the general trend now? It is a downtrend. Similarly those who shorted in 2007 Oct and don't wish to trade, just leave your short positions open for 2 years. The monthly charge is negligible compared to your gains. Most don't realise that in a bull market, the interest incurred for margin is so negligible. Your 1st, 2nd and 3rd year interest are all paid off within a few weeks in  bull run. So in margin, it is ok to just leave your stock in margin position for long term. Work it out with your calculator.    

I believe it is mindset thing. People are sold on the idea that borrowing is dangerous so they think margin is a no no. I have mentioned in previous posts long time back, the strategy is leverge only when you have paper profit and in a bull market .  In margin or CFD, you don't need to leverage if you don't wish to 

You mentioned people doing short need to cut loss. The same applies to people on long position.

Yes, not everything will be suitable for everybody just like not everybody is the same. It can't be. That is why there are winners and losers.  

Shorting by CFD is not as easy as it seems.....Firstly, one needs to have a disciplined trading mindset which cannot be accomplished by many....One needs to be emotionless when doing shorts and needs to know when to stop shorting and get the profits out or cut loss when needed......all these easily said than excecuted....The human mind is full of greed and fear, and it is not easy to be emotionless and objective....

Secondly, one needs a successful reliable trading system (which even the best trading system can only guarantee at most 70% to 80% success) that can guide one to know when to enter a short position and when to exit (cover back).....Also, one needs to calculate how much is ideal for cutting loss based on one's invested amount so that one does not cut loss too early or too late.....There is also the continual monthly fee charges for CFD to consider so that one needs to decide how long should one keep shorting to remain profitable at the end of the short....

My point is that shorting by CFD is not that easy as one will think it to be....otherwise, why will many private instituitions conduct paid courses just to teach how to short by CFD successfully through their own propriety trading systems....?
