Most Popular Algorithmic Trading Strategies (and When They Work)
Most strategies fit into a handful of buckets: momentum, mean reversion, market making, statistical arbitrage, and event-driven plays. Each category has a different dependency profile latency, borrow availability, or news feeds and that dictates whether it belongs in your stack. Think of each approach as a bundle of infrastructure requirements and risk assumptions, not just an entry signal.
Strategy Matchmaking
Before coding, document the regime the strategy relies on. Trend strategies need persistent moves and tolerate lower win rates. Mean reversion needs stable liquidity and tight spreads. Market making needs fast quote updates and robust inventory caps to survive volatile bursts. Event-driven strategies depend on clean news ingestion and deterministic rules around pre- and post-announcement windows.
Execution is not optional: a momentum system without smart order routing hands edge to the order book. A stat-arb pair trade that ignores borrow cost turns a coin flip into a bleed. Your infrastructure needs to be strategy-aware, with queue position estimates, borrow fee feeds, and venue selection logic that is compatible with the strategy’s holding period.
Where Each Strategy Thrives
Match the environment to the strategy:
- Momentum/trend-following: thrives in volatile markets with persistent direction; suffers when chop increases and transaction costs dominate
- Mean reversion: works in range-bound markets with predictable liquidity; breaks when regime shifts or spreads widen suddenly
- Market making: shines when spreads are stable and competition is predictable; demands inventory controls and fast cancel/replace APIs
- Statistical arbitrage: relies on stable correlations and low fees; must monitor borrow constraints and divergence risk
- Event-driven: profits from predictable reactions to earnings, macro releases, or protocol upgrades; needs strict filters to avoid low-quality catalysts
Guardrails that Apply Everywhere
No matter the strategy, implement these controls:
- Hard stop-loss per position and rolling max drawdown per strategy
- Circuit breakers that pause trading after N consecutive losses or slippage spikes
- Position limits tied to liquidity (ADV%) and borrowing constraints
- Post-trade analytics to validate whether fills matched your intent
Strategies fail more from execution leakage and poor risk than from entries. Pair every new idea with a checklist for fills, latency, sizing, and liquidation rules. Bake post-trade analysis into the lifecycle: tag each order with the strategy version, prevailing spread, and queue depth so you can audit performance by market condition.
