I Built an RSI Indicator in Python From Scratch (Trading Bot Ep. 2)

In this episode we build the RSI (Relative Strength Index) indicator completely from scratch in Python — no libraries, just math and pandas. RSI is one of the most widely used technical indicators in trading. By the end of this video you'll understand exactly how it works and be able to calculate it for any stock in real time. What we cover: → What RSI is and why traders use it → Calculating RSI step by step from raw price data → Plotting RSI alongside the stock price with matplotlib → Adding overbought (70) and oversold (30) threshold zones Next episode: we turn RSI into an actual trading signal. — CHAPTERS — 0:00 The finished RSI chart 0:30 Episode 1 recap 1:00 What is RSI? 3:30 Setup and data pull 6:00 Calculating RSI step by step 13:00 Plotting price and RSI 17:00 Adding overbought/oversold lines 20:00 What's next #python #algotrading #rsi #technicalanalysis #tradingbot
