IMO: for inexperienced traders not trading index futures will save a lot of hardship. indexes do not move in a direction so it is difficult to trade. you need to deal with constant changes of direction, if you are trading indexes
Ignore this advice. It is how you get experience. There is leverage, liquidity, 23 hour a day action and major moves on news. Also CME currency pairs are regulated. You can do FX without doing "cash" in the "wild west". Please come and enter the Thunder Dome.
do not trade index futres. ---> do trade index futures. IMO: for experienced & inexperienced traders, trading index futures will save a lot of hardship. index futures (as in some other commodity futures) move up down up and down down and up up and up down and down up and up and down and down ... So there are lots of trading opportunities. So catch those trading opportunities. Don't let it slip away. Alternatively don't trade. Do anything other than trading.
Index futures are some of the best products for traders, you get the clear long bias after all, and spreads are usually tight during RTH.
SP500 index has the lowest spreads (especially in options) and best liquidity at each price level relative to its volatility. Hence, it's the best instrument to choose for either newbies or seasoned traders. FX is the worst. indexes are also the only asset class that HAVE a direction. Just compare its long term returns to any other asset class (let's leave crypto out of the equation right now).
The OP is of course right. Day trading index futures is for expert traders; not for newbies. Arguably, any type of active trading is for experts. Now, the key to trade any market is of course to trade it how it is. Not how you wish it to be. On the day trading time frame, index futures generally don't trend. They gyrate. Simply put, by the time a trend is evident it's just about ready to reverse on you. So, if that's how index futures move most of the time, you'd need to develop a trading strategy which exploits that. Pure trend days are rare on index futures. About 9 % of the sample (> 7 years of intraday data) for an Up Trend Day and 4 % of the sample for a Down Trend Day.
Wrong. You have a statistical advantage when trading SP500 index over FX, commodities or bonds due to lower costs (spreads, slippage, volatility adjusted). All other things being equal, you lose less with SP500. You are talking about creating a successful strategy. That's a whole different topic. Creating a successful strategy is just as hard with any instrument. It's definitely not harder with stock indexes. It's easier actually.
The cost of trading is small for a reason. No, that's not how I interpreted the OP. Stock indices easier compared to what exactly? In theory, the easiest market would be very directional going from A to B in a linear fashion with zero noise. In practice, stock index futures are very different from that and generally are very complex instruments by design.
