Hi 3b8yer,
Welcome to T2W.
Your question isn't stupid at all although, as others have pointed out, your intention to risk a large some of money when (by your own admission) you don't know what you're doing is what will probably
'make a lot of eyes roll, cause a lot of sighs and if not, will probably bring . . .'
The relationship between different markets is further complicated by the relationship between the cash market and the futures market. If you're trading via a spread bet broker and taking a punt on the FTSE 100 cash index then, IMO, you would benefit enormously by keeping at least one eye on what the futures are doing. When the U.S. opens at 2.30pm U.K. time, this means looking at something like the ES (the e-mini futures contract based on the S&P 500 equity index). If you're not clear about the relationship between cash and futures and why it's so important, the
Essentials Of 'Indices' Sticky offers some insight to the topic.
If you go ahead with your proposed trade - there are two probable outcomes:
1. You'll make a killing and then think all the nay sayers on your thread aren't worth listening to. You'll then rinse and repeat hoping for the same outcome next time and the time after that. If you go down this road, I - and most other long term members here - will absolutely guarantee 100% that you'll blow your whole account away in due course. And probably sooner rather than later.
2. If you don't take the trade it will probably go in the direction that you imagined it would and you'll be kicking yourself for listening to the likes of me. However, you will have done the right thing. Most folks on here take joy from any trade that ends in a profit. The hardened pros are different: they'll take more pleasure from a losing trade executed to perfection for the right reasons than they will from a winning trade executed for the wrong ones. In that respect, trading isn't about being right or wrong, it's about doing the right thing (and not doing the wrong thing) at any given time. Without exception, punting large sums when you don't have experience backed by a positive expectancy is always the wrong thing to do. Of course, that assumes you're not deliberately wanting to blow your entire account in double quick time!
