Position trader (short term) — the most common type. Gets into trades frequently, but closes his positions before low liquidity periods (holidays, summer vacations, etc.)
Long term investor or hodler — his trades can span several years, which he will only close upon major trend shifts.
Scalper — does a lot of short trades that can last as little as just a few seconds. As a rule, each trade is rather inconsequential, but in the long-term perspective, they add up to a nice profit overall.
