The definition of a professional trader is, "professional" meaning a method to support oneself financially and secondly "trader" describing the type of activity, thus a professional trader makes their living in the markets.
According to our most trusted news site, CNN. The average salary for a freshly minted CS grad is $60,872 which means:
- $5,072 / month
- $1,268 / week
- $253 / biz day
Now if we break that $253 / day into HF style trades it looks like
@ 1 share/ day -> $253 net gain / share
@ 10 share / day -> $25.3 net gain / share
@ 100 share / day -> $2.53 net gain / share
@ 1000 share / day -> $.253 net gain / share
@ 10,000 share / day -> $.0253 net gain / share
@ 100,000 share / day -> $.00253 net gain / share
At 100K shares / day with a *net* pnl per share of 0.253cents (less than a penny) we could make it work. At 10k shares / day with 2.53 cents / share profit also in the realm of feasibility. Note that 25 cents / share profit for every share is possible but think your pushing it to expect that consistently day-in-day-out in high volume. Remember this is per share, not per trade.
Now lets say we choose 10k shares @ 2.543cents / share net pnl, e.g. we`re trading the spread+a tick or two and our edge is say 10%. Meaning 60% of our trades make that 2.543cents, and 40% of the trades loose 2.54 cents, NOTE: in reality that kind of equally priced distribution abs(win) == abs(loss) is highly unlikely.
Result is we actually need to trade
$254 = k * (0.6 * 0.0253 - 0.4 * 0.253) where k = 50K, so our 10K shares is now 50K shares.
Counting in trades lets say we`re trading lots of 100 shares, meaning we`re doing 500 trades / day. And lets say the market is open 6H / day which means 500 trades equally spaced is 6 H * 60Min * 60Sec / 500 trades = 43.2sec. e.g. thats one trade every 43.secs for 6 hours but actually its half that because you need to enter/exit the position, so we`re doing 1 trade every 21.6 seconds.

It starts to put this HF trading thing in perspective -> 1 trade every 21.6secs that makes 2.5 cents/ share on average, to makes $250 / day or $60K / year..... a nice healthy dose of reality.
What im doing now is diversifying my income strategies. Some of this is trading strategies, some un-related and others quite frankly you just would not believe. Having 20/20 hindsight theres so many things I would have done differently, but easily the most important would be to build non-trading income strategies, that cover your bills when the trading hits a rough patch - because when your starting out its just one endless bumpy rough ride.
