Guide 📈 Algo trading basics: what bots actually do (and why most of them lose)

Somewhere out there a YouTube ad is promising you a bot that "prints money while you sleep". This is the honest version of what algorithmic trading actually is, written so you never fall for that ad.

🤖 What an algo actually is
Strip the hype and an algo trading system is three boring parts:

1. Rules — "if price crosses above the 50-day average with high volume, buy; exit at 2% stop-loss"
   
2. Data — a live feed to check those rules against
   
3. Execution — an API connection that places the orders
   

That's it. No magic brain. A bot just does exactly what you told it, instantly and without fear or greed. If your rules are bad, it loses money superbly fast and without emotion.

🏦 Where retail algos actually run

• Indian stocks — broker APIs: Zerodha Kite Connect, Upstox, Angel One SmartAPI (this is the legit "algo" scene in India, not WhatsApp bots)
  
• Crypto — exchange APIs (Binance etc.) — the easiest place to experiment because APIs are free and markets never close
  
• Forex/CFDs — MetaTrader (MT4/MT5) "Expert Advisors" — oldest retail ecosystem, most snake oil sold
  

🧪 The only sane learning order

1. Learn enough Python + pandas to load price data (2–3 weeks of evenings)
   
2. Backtest a dead-simple strategy on historical data (backtrader or vectorbt)
   
3. Paper trade it live for 3 months minimum — fake money, real market
   
4. Only then: real money, position sizes so small that losing them is boring
   

Skip to step 4 and the market will teach the syllabus in a harsher order.

⚰️ The 3 backtest killers (why "90% win rate" screenshots lie)

• Overfitting — tune enough knobs and any strategy "wins" on past data while dying on live data. Fewer rules = more truth.
  
• Look-ahead bias — accidentally using today's closing price to decide this morning's trade. The classic self-deception.
  
• Survivorship bias — testing only on stocks that still exist ignores the ones that went to zero.
  

Plus the silent fourth: costs. Brokerage, taxes, slippage (you rarely get the backtest's price) eat thin retail edges alive.

📊 Realistic expectations
Retail algos don't win with speed — institutions own speed but not discipline. A humble retail algo that risks small, trades rarely and survives is a legitimate thing. A bot promising 5% a month guaranteed is a Ponzi with a GitHub repo.

🚩 Scam radar (memorise)

• "Guaranteed returns" bot / "SEBI-registered profit sharing" on Telegram → scam
  
• Anyone selling a bot with amazing backtests but no live audited track record → ask why they'd sell a money printer for ₹999
  
• "Copy-signals" channels charging subscriptions → you're the product
