What leveraged products do you usually trade? What level of gearing are you looking for?

There is no evidence, that these products do (long-term) good to investors, I feel

I done tons of leverage, from FX trading, to options, to future tradings.

I say only 1 form of leverage is not so volatile and still acceptable. USA stock brokerage allow 1:4 stock buying and 1:2 stock maintainence.

Thats the max I feel is acceptable. And even that can be extremely painful when your stock portfolio moves down rapidly.

Be careful!
