Episode 70 ... Jeff Davis (76:31)

  • Grew up in farm country two hours north of New York
  • [Sounds like a two pack a day smoker]
  • Didn't go to college
  • Worked for US postal service, in processing center, night shift
  • Voracious reader of magazines and newspapers at work
  • 30 years old then [late 1990s?], married, had baby and mortgage
  • Wanted to be his own boss, attracted to day trading
  • $25,000 minimum to join an LLC trading firm
  • 1999, Harbor Securities, firm blown up by one trader [not him]
  • Didn't matter since he'd pretty much lost all his money anyway
  • Saved more money, went to Bright Trading next
  • Passed series 7, sat on a desk in the city, surrounded by traders
  • Worked night shift at USPS, day traded during day, slept on train [wow]
  • Was breakeven at Bright
  • March 2000 he went full time [how about that timing?]
  • Learned how not to lose while at Bright
  • Learned how to short
  • At Bright, you picked one stock and specialized in it
  • Trade with the specialist, not against him
  • Most of his problems were mainly him
  • Made money in the morning, gave it back in the afternoon
  • Sep. 11, 2001 last day of trading at office at Bright (next to Towers)
  • Afterwards traded from home, lonely and hard but also good
  • Guys who focused made money, people who didn't adapt were gone
  • Got Lyme Disease, got sick, couldn't trade ... inspired him to automate
  • You can't fiddle along with trading, bad things happen in life so you have to seize opportunities
  • Exchanged his mentoring with a programmer who coded up a "tape reading tool"
  • In 2005, Russell re-balance provided a lot of opportunities, he saw this
  • His brother also a computer programmer, wrote a program to take advantage of index rebalancing
  • Found programmers who also traded, they understood what he wanted
  • Should have learned Fortran and Cobol in high school but didn't
  • In his early 50s now, wouldn't even think about learning how to program now
  • If you're in your 20s, definitely learn how to program, or find someone who can program for you
  • Avoid the rabbit holes
  • If you're searching for edge, you're definitely going to go down some rabbit holes (curve fitting, etc.)
  • Nobody has ever run a bad backtest
  • Trend following hard to do when you have a 30-40% win rate, people give up
  • Nothing out of the can is going to work for everybody [or anybody]
  • You have to work hardest on you .. your psychology
  • Your strategy has to fit your personality
  • He has now achieved "mature simplicity" ... it's not what you add, it's what you take away, less is more
  • Find something where you can get size on, where you're confident
  • You're in a risk business, you don't want to make a salaryman's wage
  • His algorithm is now trading the S&P futures
  • Mean reversion strategy -- most days are range days
  • Range prediction algorithm -- knows probability of daily range, will fade spikes
  • Yesterday's high or low is hit 88% of the time
  • VWAP is the target on most of his trades
  • When price gets away from VWAP, that's where he gets interested
  • Range is a well-kept secret (Cooper, Crabel, Raschke have done lots of work on it)
  • Be aware of "market regime" even though you're day trading
  • Everything he does is based on Average True Range
  • For example, a 22 handle move will revert at least 5 handles 70% of the time
  • People can't stick with their systems
  • Automated systems with tight stops don't work -- then you fiddle with the stops
  • Old traders just do the same thing in the same way every day
  • When you're trading right, it's boring, it's just execution
  • Throw away what the crowd is doing
  • So much trading wisdom from the past ("the trend is your friend") not relevant for day traders
  • Don't be a hamster on a wheel
  • You have to stick with your system, only possible if it fits your personality
  • "Averaging is groping for the top or bottom"
  • He doesn't scale, he just goes all in [scales out in two pieces however]
  • He never chases
  • If nothing sets up, don't push the button
  • Picture a pool filled with sharks, that's what you're jumping into to make money
  • Overtrading is the downfall of most failing traders
  • Many are operating on tilt, jumping from strategy from strategy
  • Always knows what he's risking, structured identically, dollar loss pre-determined
  • No slippage on his stops in SP futures
  • Traders always rode in last train car in case of derailment [always thinking about risk]
  • Good traders are not jacks of all trades, they specialize
  • Your strategy has to be about getting size on, otherwise there's no point
  • "Single digit midgets"
  • You get confidence from specializing
  • Two regimes: expansion and contraction
  • Tracks range of one minute SP to make sure his stop is "outside of the noise"
  • He went from having tight stops to having wide stops -- to protect him from himself
  • He knows the percentage of the time his wide stop will get hit -- he never fiddles with it
  • With tight stops, he'd be liable to fiddle with them
  • You need to be able to trade your system without feeling the urge to fiddle with it
  • Once comfortable with strategy, with your stops, your dollar losses, then you can build up your size
  • Exits in two pieces: first piece getting him 2.5 points on average, gets instant gratification, lets second piece take its time (averaging 7 points) 
  • Two to one win rate on his mean reversion trades [1R losers, 4.75R winners]
  • He's out there to help people, esp. persistent guys who don't lose money but don't make big money
  • Day trading is not a hobby, not an action junkie thing, it's a business, take it seriously
  • Says some kind things to Aaron in parting
