I have some brain damage too. Then I discovered that some people can become genius from brain damage and is a real phenonmenon. Not suggesting you should intentionally give yourself brain damage to be a successful trader.
There will be warning signs. The market will not fall off a razor edged cliff. Volatility will begin to ramp up most often failing a nuclear strike on the White House totally out of the blue. Even then, knowing this market, it will go up again, wouldn't surprise me.
I don't know, according to some analysts on CNBC, the warning signs have been there on and off since 2013.
You have to take those warning signs seriously! They successfully predicted 22 out of the last 4 recessions.
I don't know anyone who has not had same or far more time spent to achieve to become consistent. When so many are saying 5%, I believe the 5% are at end of the year they didn't lose money, but most of the percentages are not making huge money. I an thinking 3-4% are breaking even or making under $20k, a whole lot of work to be making a whole lot less than many think. The guy who has a $20k account has a much better shot of huge percentage returns than another with 5 million account. The numbers mess with your head for one, and many will diversify which in a way loses percentages. I often wonder what the percentages of Hedge funds that actually hedge? Bet that figure is very low. Hedging is very expensive in terms of outlay of account funds between margins and options, options don't go one for one till expiration, but in my case, I have extreme low winning percentages in futures, so hedging is very necessary. I had a very good job after the military 3 year hitch, I took more a philosophical approach to trading, me against me on how to pay/play the game. I never realized how addictive this would become to not lose money. I still put in 70 hour weeks, but it all automation and seldom watch it.
