1MM to day trade? Are you so rich and out of touch you don't realize how big a number that is? That's almost as absurd as saying let's raise the age of consent to 50. No thanks.
I typed an extra M.
1,000,000 should be the minimum required capital to daytrade, among having at least a few series exams. To accomplish this abolish the sponsorship requirement for exams so that daytraders who wish to trade can get education demonstrating they understand the risk.
Day trading is gambling. There is no edge in day trading. If there is a population of 3M day traders, 1/10 of 1% of them probably understand enough about digital signal processing to
properly recover information from a high frequency time series such as the 1m chart. To all the people who think they do fine. In a population of 3M traders there will be winners. Entire fields of science are dedicated to learning as much as we can about these time series for radio and medicine. Some piker with a few lines on a chart has
zero idea what they are doing.
Have you ever sat down and asked yourself why day trading is even allowed? Casinos have to have regulated odds. For example, you can theoretically know to the Nth decimal place your odds of hitting 00 on roulette (the odds of you hitting 00 on roulette are still better than discovering a consistent edge in the high frequency time frames on a future). With trading you can't. This makes it hard for the broker to hedge against risk such as the one in OP's post.
So what are the options?
1. Allow day trading and require 1/2 notional for any contract up front and the other 1/2 in escrow. For well capitalized traders (1M+) these can be reduced some fractional percentage.
2. Ban day trading outrights (spreads with SPAN margining are fine since spreads negate risk considerably). Raise margin on everything across the board.
Imagine you're a broker. I, a college kid with $3000 to my name, say "I would like to buy 1 CL contract". You, the broker, would be insane to say "yeah sure kid no problem". I will come to you and say "but I am providing liquidity by getting in and out of trades quickly" to which you laugh at me and point to a corner office labeled "citadel" and another labeled "jane street". Then, you walk me over to the pit and tell me if I want to day trade I can buy a seat. Don't like the trading analogy? How about a house. Do mortgage brokers allow 2.5% down for people with bad credit and no income? Not anymore. Mortgage brokers were gambling with the same risks as day traders in 2008 (also funded by the taxpayer...funny enough). We saw how well that worked out. Now you'd be lucky to get a 5% PMI as a well off silicon valley software engineer with an 800 credit score. Margins necessarily have to increase for people with poor credit scores (i.e. day traders) in order to compensate the broker fairly for their risk.
The internet has brought unprecedented risk to people who are not involved in day trading. Flash crashes are becoming more frequent, for example. Why should I, a guy who holds a spread and/or underlying for months at a time, be put at unnecessary risk because you have a gambling problem? I shouldn't. The brokers are protected by taxpayer bailouts. Next time you're out - thank a taxpayer for funding your addiction to losing money.
