<h1> 10 Python Scripts Every NSE Trader Needs (With Code)<em>DOYR | Not financial/legal/tax advice. For educational purposes only.</em>---If you're an NSE retail trader in 2026 and you're not using Python, you're leaving money on the table.Not because Python is magic. But because Python can do in 2 seconds what takes you 2 hours manually.I've been building trading tools on Termux/Android for the last 2 years. Here are the <strong>10 Python scripts</strong> I use every single day.All code is free. All tools are free. You can run this on your phone.### Why Python + Termux = SuperpowerMost traders think coding is only for "tech people" or "professionals." That's a lie.Python is:- <strong>Easy to learn</strong> — Readable like English- <strong>Free</strong> — No license, no subscription- <strong>Powerful</strong> — Can fetch data, analyze, send alerts- <strong>Portable</strong> — Runs on phone, laptop, cloudTermux turns your Android phone into a <strong>full Linux machine</strong>. You get:- Python 3.13- pip package manager- Git, curl, wget- cron for scheduling- Full filesystem accessCombined, Python + Termux = a <strong>complete trading workstation</strong> in your pocket.### What These Scripts Will Do For You| Time Saved | Script | Manual Time | Automated Time ||------------|--------|-------------|----------------|| Daily | Price fetcher | 5 min | 5 sec || Daily | Top gainers/losers | 15 min | 10 sec || Daily | FII/DII tracker | 10 min | 5 sec || Weekly | Stock screener | 2 hours | 30 sec || Daily | Option chain analyzer | 10 min | 2 sec || Daily | Telegram alerts | Manual checking | Instant || Weekly | Backtest runner | 4 hours | 1 min || Daily | Portfolio tracker | 30 min | 5 sec || Daily | News sentiment | 20 min | 10 sec || Daily | Report generator | 30 min | 2 sec |<strong>Total time saved:</strong> 6+ hours per week*<em>Value:</em>* ₹10,000+ per month if you bill yourself at ₹500/hour### PrerequisitesBefore running these scripts, make sure you have:1. <strong>Termux installed</strong> from F-Droid (NOT Play Store)2. <strong>Python 3.9+</strong> installed (<code>pkg install python</code>)3. <strong>pip</strong> working (<code>pip install pandas numpy requests xgboost</code>)4. <strong>Internet connection</strong> (4G/WiFi)That's it. No fancy hardware. No expensive subscriptions.### How to Use This GuideI recommend reading this in order. Start with Script 1, master it, then move to Script 2. Don't try to implement all 10 in one day.<strong>Week 1:</strong> Scripts 1-3 (basic data fetching)<strong>Week 2:</strong> Scripts 4-6 (analysis + alerts)<strong>Week 3:</strong> Scripts 7-9 (backtesting + sentiment)<strong>Week 4:</strong> Script 10 + automationBy the end of the month, you'll have a complete trading toolkit.### Important Notes Before You Start1. <strong>API limitations:</strong> NSE API may block requests from Termux. Always have a fallback (Yahoo Finance, web scraping).2. <strong>Rate limits:</strong> Don't run scripts every 5 seconds. Add delays. Respect APIs.3. <strong>Data accuracy:</strong> Free APIs have delays. For critical trades, verify with your broker app.4. <strong>Disclaimer:</strong> These scripts are for educational purposes. Not financial advice. Test before live trading.5. <strong>Backup:</strong> Always backup your code. Use Git. Don't lose 20 hours of work.### Troubleshooting Common Issues*<em>Issue 1: NSE API blocked</em><em>- NSE blocks requests from unknown IPs- Solution: Add headers, use session cookies, or switch to Yahoo Finance</em><em>Issue 2: Module not found</em><em>- Run: <code>pip install module_name</code>- Or use <code>pip3</code> if <code>pip</code> doesn't work</em><em>Issue 3: Script runs slow</em><em>- Add caching (save data to file, don't fetch every time)- Use async requests- Reduce data frequency (use 5min instead of 1min)</em><em>Issue 4: Telegram bot not working</em><em>- Verify bot token with @BotFather- Check chat ID (use @getidsbot)- Ensure bot is added to group/chan
