I have day traded Big S&P500/ES for 31 years, took 7 years to get profitable and another 7 to learn scalping. There are other markets less as difficult than ES cause ES is used often as a hedge for the cash index. And you are wrong, when you on wrong side of a move, it is damn hard to get out, as it should be of any market. So many think ES is cheap trading, but CME gets much more money now than when there was Big S&P at $500 a point. I now have to trade ten times more contracts than before, but there is not ten times more volume at all. I now spend my time designing longer term methods and learning more on options.
1-3. I only day trade(automation) first hour of most markets, biggest volume, sizeable moves, I am in profitable trades right now at 1 minutes 45 seconds ave time, I use one minute bars for heavier volume instruments. I use other timeframes for other instruments that back test well that are traded 23 hours for other than scalping methods. Generally going against the crowd. I have one system that only used 60 minute timeframe and can stay in overnight, follows 23 hours and over 40 markets. Always use volume, but my definitions are often opposite of how stocks are traded.
4- . I don't use any indicators under the chart, none of those indicators for day trading but do use for weekly/daily. Scalping I use Bollinger Bands and Slow moving averages, speed gives too many false signals for me. Bar charts, Dome(spend couple years watching it as can aid sometimes), ES use to be mental stops, but retail should use hard stops.
10/11. I don't expect anything and often think this is silly and puts undue stress on the trader. Risk less than 1%
12. Stop trading ES at minus 9 points per lot in one day on original entries, less than 1% to 1.5%.
13. no/no/yes
As a Scalper who averages down on every signal, like Sept 9 and 12 were losing days for me, those days were hard trending days, my systems don't do well on these types of days. Lucky for me on Sept 12, price bars set off triggers within the system that turns trading off for twenty minutes so I lost minimal on Sept 12, and I believe it set off three triggers so whatever trading done, wasn't much. After having two losing days in a row, I increase size 50%.
If I was just starting out, learn options on stocks. People don't realize how much you have to remember in seconds. Say you are a corner of busy intersection, and you witness head on accident between two cars, what do you do? If you stand there, you lost; if you noticed one was newer Volvo and other 20 year old Ford-you dash to driver side of Ford calling 911, then start talking to driver and check if others in car, if others crying from pain-you know they are alive. You have to make dozen split second decisions if you going to help. Trading is very similar, which signals do you disregard and which do you take.
