一覽

High-frequency trading (HFT) exploits price differences that exist for microseconds. Firms spend $100M+ on colocation, custom silicon, and optimized code to shave nanoseconds. Practitioners combine systems engineering, low-level optimization, and market microstructure knowledge. Compensation: $200k-$1M+ annually (senior traders/engineers). Mastery takes 2-3 years of intensive work. Very high barrier to entry; only 100-200 practitioners globally.

什麼是 HFT & Low-Latency Trading

High-frequency trading (HFT) is the practice of exploiting microsecond-scale price discrepancies between markets or instruments. Traders use custom silicon, colocation, and ultra-optimized code to execute thousands of trades per second. Advanced practitioners blend systems engineering (kernel optimization, FPGA programming), market microstructure (understanding order flow), and quantitative trading (building statistical models). They work for proprietary trading firms (Renaissance, Citadel, Jump Trading) or build systems for them.

❓ 常見問題

What's the difference between HFT and algorithmic trading?
Algo trading: algorithms executing large orders (minutes-hours timescale). HFT: exploiting microsecond mispricings (much faster). HFT is more complex, requires custom hardware/colocation. Not all algo traders are HFT; most HFT firms are also algo traders.
How much latency advantage is worth pursuing?
10 microseconds: worth $millions if you can capture price difference. 100 microseconds: worth less (market moves more). 1 millisecond: probably not worth custom hardware. Industry spends millions to save 10-50 microseconds. Asymptotic returns: each microsecond costs more to save.
What's the role of colocation?
Exchanges host servers in same data center as exchange matching engine. Reduces latency from network: 100+ microseconds down to 10-20 microseconds. Firms pay $100k+ monthly for colocation. Critical for HFT competitiveness.
Can an individual trade HFT?
Technically yes, but not competitively. You'd need $10M+ capital, custom infrastructure, regulatory approval. HFT dominated by firms (Renaissance, Citadel, Jump Trading). Individual HFT unlikely to beat the pros. Better: learn systems programming elsewhere.
Is HFT legal?
Yes, but heavily regulated. SEC/FINRA restrict naked access, require kill switches, ban spoofing (fake orders to move price). Compliance costs are substantial. Legitimate HFT provides liquidity; illegitimate HFT manipulates. Regulation tightening.
