Building a Simple Algo Strategy | 2025 Proven Beginner’s Guide
Building a simple algo strategy doesn’t need rocket science. With a clear rule, basic coding, and proper backtesting, even beginners can automate trades. In 2025, NSE and SEBI regulations support retail algo traders, making it easier to design, test, and deploy strategies step by step.
From Idea to Backtest in 30 Minutes
Picture this: You notice that whenever the 50-day moving average crosses above the 200-day moving average, stocks like Infosys or Reliance tend to trend higher. Instead of manually checking charts, you write a rule, backtest it, and let an algorithm trade it for you.
That’s what building a simple algo strategy is about — turning an idea into a rule that executes consistently, without emotions.
What Makes an Algo Strategy “Simple”?
Simplicity in algo trading means:
One clear signal (e.g., SMA crossover).
One filter (volume > average).
One exit rule (stop-loss or target).
Fixed risk management (1–2% per trade).
👉 Example: Buy when SMA50 > SMA200, sell when opposite happens, with a 2% stop-loss.
For basics, see Investopedia on Moving Averages.
Core Example: SMA Crossover Strategy
The Simple Moving Average (SMA) crossover is a favorite for beginners.
Buy signal: 50-day SMA crosses above 200-day SMA.
Sell signal: 50-day SMA crosses below 200-day SMA.
Exit: Either opposite signal or stop-loss via ATR (Average True Range).
👉 This works on NSE stocks like TCS, Infosys, or even Nifty index futures.
Data & Tools Needed
You don’t need Wall Street servers. Start with:
Data: OHLC (Open-High-Low-Close) from NSE India.
Tools: Python, pandas, TA-Lib, or simple Excel.
Backtesting platform: Broker APIs, or even free Python libraries.
Documentation: TA-Lib for Python.
How to Backtest a Simple Algo Strategy
Backtesting = checking how your rule would have performed on past data.
Steps:
Split data (train/test).
Apply rules → generate buy/sell signals.
Track metrics: CAGR, win rate, Sharpe ratio, max drawdown.
Include brokerage and slippage costs.

Risk Management is the Real Strategy
An algo without risk control is dangerous. Always set:
Stop-loss: 1R (risk unit) or ATR-based.
Position sizing: fixed % per trade.
Capital allocation: never >10% on one stock.
Max daily loss: hard limit.
This ensures your algo doesn’t blow up capital on one bad trade.
From Paper Trade to Live Deployment
Step 1: Paper trade on demo accounts.
Step 2: Live trade with small capital.
Step 3: Scale gradually after consistent results.
Brokers like Zerodha and Upstox provide APIs for automation (check SEBI guidelines). Always log trades and review results weekly.
Common Mistakes Beginners Make
Overfitting: Making the strategy work “too perfectly” on past data.
Ignoring costs: Brokerage + slippage can eat profits.
Tiny samples: Backtesting on 6 months = unreliable.
No risk limits: One black swan event can wipe accounts.
👉 Discussions on Reddit AlgoTrading highlight how over-optimization destroys live results.
Key Takeaways
Building a simple algo strategy = clear rule + test + execute.
Use SMA crossover as a beginner-friendly starting point.
Always backtest with costs + risk control.
Deploy gradually (paper → live).
In 2025, SEBI/NSE make algo trading accessible for retail traders in India.
