hello all, this newbie would like to ask some qs Im planning to do trading as an investment, for long term. I know that for short term there are a lot of fluctuations , but if we look in a long term perspective, from year to year , how many percent does the price increase yearly? and how exactly the energy futures differ from normal company stocks? what are the media/ website if we wanna trade online (I'm staying in Singapore)? is there any fee required?
