I used to trade all long term stuff in Energy Markets and before that for a retail fund across all exchange derivative products. In those days had analysts and loads of support and I knew a lot about fundamentals of everything.
Scalping arrived after a chance meeting with an x-collegue, when I started trading for my own account. I have to say I am glad I found it because I am in no doubt that when the markets are moving there is no better way to make a healthy consistent return. I still trade other things to and do a lot of systems work, bit like research that, mostly fruitless but now and again something good. I now run systems on FX and Indices but still make more money scalping, probably a confidence thing more than anything else.
A few years ago I built an automated portfolio model for 23 commodity futures and tried to start a fund. Commodities were not in vogue then and I struggled to get more than a few mil together to trade it, considering I was just on profit share and had business costs it never did get off the ground. Still have the software however so one day I may do it again. Certainly was an interesting lesson in understanding technical market dynamics. Actually think that developing automated systems is the best way to learn about how price moves, by analysing signals a system produces and where it is going wrong you learn far more than by just looking at an historical chart.
OK...market must be quiet, I am quite obviously rambling on.
Good luck with CPI this afternoon, I do not hold out too much hope but hoping I can reduce my exposure a bit before the weekend, right now, that would be enough.
