RookieCharts
Crypto pattern detection for beginners. Automatically detects 20 chart patterns across 5 cryptocurrencies, explains them in plain English, and includes a strategy backtester.
The Problem: Crypto Charts Are Intimidating
Cryptocurrency trading has exploded in popularity — but the tools built for it are designed for experienced traders. Beginners who want to learn chart reading face a wall of jargon, complex indicators, and overwhelming interfaces.
The result? New traders either give up entirely or make uninformed decisions based on hype and social media tips. There was no platform that could automatically detect chart patterns and explain what they mean in plain language — bridging the gap between raw market data and actionable understanding.
Our client wanted to build a tool that could democratize technical analysis for crypto beginners — making chart patterns accessible to anyone, regardless of their trading experience.
What We Built
RookieCharts is a crypto pattern detection platform designed specifically for beginners. It automatically scans 5 major cryptocurrencies (BTC, ETH, SOL, XRP, DOGE) across 4 timeframes, detects 20 different chart patterns, and explains each one in plain English.
Automated Pattern Detection Engine
The core of RookieCharts is a mathematical pattern detection system built with scipy signal processing. It runs 24/7, scanning price data from the Kraken exchange API, identifying patterns like Head & Shoulders, Double Bottoms, Ascending Triangles, Cup & Handle, and 16 others. Each detection includes confidence scores (typically 75-95%) and visual markers overlaid on interactive TradingView charts.
Plain English Explanations
Every detected pattern comes with a jargon-free breakdown: what the pattern means, what typically happens next, and visual diagrams. This is what sets RookieCharts apart — it's not just detection, it's education.
Strategy Backtester
We built a comprehensive backtesting engine that lets users test trading strategies against 2+ years of historical data. It supports RSI, Moving Average, Pattern-Based, and DCA strategies with configurable parameters. The optimizer tests 243+ parameter combinations to find the best-performing setups, showing P&L, win rates, max drawdown, and Sharpe ratio.
Paper Trading Simulator
Users can practice trading with live market data without risking real money. The simulator tracks performance, win rates, and portfolio value — building confidence before committing capital.
DCA Calculator
A dollar-cost averaging calculator that shows historical returns for any coin, configurable by amount, frequency, and time period.
Automated Content Pipeline
We built an automated blog and social media system that generates weekly pattern recaps and monthly market reports, auto-posted to the platform's blog and X/Twitter account.
