Algorithmic Bitcoin Trading Bot

Starting capital: $10. Goal: grow it through automated trades using a multi-indicator signal system. RSI + EMA crossovers + MACD + Bollinger Bands combined into a single -1 to +1 score. Entry threshold, risk per trade, take-profit and stop-loss all configurable. Currently running grid search over parameters on Binance historical 4H data.

Dev log

What shipped, broke, and learned.

May 2026
BTC Bot: Grid search over entry_threshold (0.25 to 0.55) and risk_per_trade (0.15 to 0.40) on Binance historical 4H data. Best combo so far: threshold 0.40, risk 0.25. Sharpe climbs to 3.1.
Apr 2026
BTC Bot: Switched from fixed TP/SL to ATR-based exits. Drawdown reduced 12%. Adding Telegram alert hook next.
Mar 2026
Scraper Platform: Proxy pool burned through 3 providers. Settled on rotating residential proxies with fingerprint randomization. 94% success rate on target sites.
Feb 2026
Fruit Classifier: Shipped to client. Model running on Jetson Nano at 28fps. False positive rate on bruising down to 4% after re-labeling 800 images.
Jan 2026
Vending Machine: PCB v2 done. Stepper drivers replaced with better heat management. QR payment flow integrated with local payment gateway. Test transactions passing.
Nov 2025
ROS2 Nav Stack: Costmaps tuned, robot reliably navigates a 6m x 4m room. Next: dynamic obstacle avoidance and goal cancellation on emergency stop.
Got a weird idea you want to build?
If it's technical and has real constraints, let's talk.
