Hi danboi8989,
Apologies, you did indeed say you're only demo trading. When I read your OP, I got the impression (perhaps wrongly) that you had been trading real money and would do so again as soon as you found a job.
With regard to ideas, I'd suggest you stick to one thing at a time, i.e. one market and timeframes based around either day trading or swing trading. Most members (but not all) will advise against day trading with a spread betting account. Once you really know a market - and understand its pros and cons - you can then make an objective decision as to whether you want to stick with it or move on to another one. Check out the Trading Plan Template in my signature - there's lots of ideas in there which should help in this regard.
Sure, there are the trading equivalents to Usain Bolt. Then there's the rest of us! FWIW, I don't know of and, in the 10 years I've been a member of T2W, I don't recall hearing about - a single trader who successfully trades multiple markets in multiple timeframes. I've met traders who - for example - day trade US stocks and swing trade UK stocks. Or index futures traders who occasionally - and with good reason - trade some commodity futures. It's quite common for equities traders to trade the index futures - as they invariably look at the main market index as much as they do individual stocks. But that's as far as it goes.
The problem with mixing and matching is that you'll never get a sufficient body of trades to analyse in order to work out the key ratios that tell you whether or not you're onto something. If anyone is able to develop a profitable strategy that can be traded across multiple markets and timeframes - then I'll bet they're extremely experienced and are walking encyclopedias of all the markets. It's possible in theory I suppose - but I certainly can't think of anyone that's ever achieved it.
Tim.
