So are you profitable day trading SPX?While it is possible to make very good money trading SPX, NO ONE is making 100% ROI consistently, over time, although it might be possible to make 100% of your initial investment over a short period of time IF you start with a relatively small balance (Most brokers will require you to have at least $2000 in your margin account of which only half is available for trading options) AND you're willing to risk all that is available with each trade, AND you WIN EVERY TIME. But if you do risk it all and discover that you need to make an adjustment to your trade, you will not be able to because you will not have sufficient liquidity available to make the adjustment. So, don't believe this person because you are not being told the whole story.
If you want to Day Trade SPX, before you even fund a brokerage account, open a paper trading account and become intimately familiar with SPX. Don't waste time looking at anything else because, while SPX isn't totally unique, it does come pretty damned close. Set you trading balance in your PAPER ACCOUNT to equal your risk capital to make it more realistic. Become familiar with credit spreads (Put and Call), Iron Condors and Broken-Wing Butterflies. Some of those are directional but Condors are not.
Become familiar with a good chart. I, personally, like Trading View (Google it) and how to read the signals it contains. Successfully Day Trading SPX requires you to have a solid understanding of what the markets (SPX is the index for the S&P 500 which includes all of the Dow plus just under 500 other publicly traded large cap stocks) so it is a good indicator of what is happening in the world of equities. Understand that it can and HAS moved $300 in a 24 hour period. If you are day trading you will only be trading on Expiration days, usually Mondays, Wednesday and Fridays.
Learn to gain COMPLETE control of your emotions. if you are not able to do that, then do NOT EVEN CONSIDER day trading SPX or anything else. You will quickly become suicidal. Get to know SPX better than you know your spouse or your children but don't neglect them for the sake of getting to know SPX. Don't waste time with other derivatives, especially stock options. SPX is unlike ANY stock based derivative.
Success Day Trading SPX is a function of Discipline, Emotional Control, Knowledge of the markets and knowing that the financial rewards (ROI) are a function of all those things plus the risk you are able and willing to take.
You made a bunch of God and Motherhood statements that are very difficult to implement in practice. The only trader I know that has done well day trading SPX is @jeffalvinson, an excellent individual. But it took him years of experimenting and system development to achieve his results. I tried, even with some helps from him, but just couldn't make it work.
If you are interested, search and read all his posts. He was very generous in sharing the basic concepts, very informative and profound. I wasn't able to day trade options using his approach but benefited by applying his concepts to swing trade options.
