Building a crypto trading bot: why engineering matters more than strategy

·3 views

A technical guide from Xingyao Byte argues that trading bot strategy accounts for only about 10% of success, with the remaining 90% depending on robust engineering infrastructure. Key components include proper handling of exchange APIs via REST and WebSocket connections, with careful management of rate limits, reconnections, and request authentication. The guide emphasizes that every order must carry a client-generated ID to prevent duplicate submissions during network timeouts, and that local bot state must be periodically reconciled against the exchange as the authoritative source of truth. A dedicated risk layer — enforcing position limits, daily loss kill switches, and dead-man's switches — must operate independently of and above the trading strategy. The article concludes that durable bots are distinguished not by clever signals but by their ability to safely handle infrastructure failures such as dropped connections, double submissions, and sudden market crashes.

How Ditching WordPress Early Pushed Two Developers to Build a Custom Tech Stack

Developers Andrés and his partner initially used WordPress to build websites but found its plugin dependencies, update conflicts, and limited customizability frustrating. Rather than mastering WordPress management, they chose to learn web development from scratch, starting with React and later adopting Next.js. Each client project organically expanded their skills across technologies like AWS, Supabase, PostgreSQL, and various third-party services. The duo, who now run Developwave, emphasize that their stack is always chosen based on the specific problem at hand rather than a fixed preference. They acknowledge WordPress still suits simple use cases, but prefer the flexibility of custom builds for businesses with specific needs.

How to Use the Haversine Formula to Calculate GPS Distance in JavaScript

Calculating real-world distance between two GPS coordinates requires accounting for Earth's curvature, as simple arithmetic on latitude and longitude values produces meaningless results. The Haversine formula offers a practical solution by computing the great-circle distance between two points on a sphere using their coordinates. A JavaScript implementation involves converting degrees to radians, applying trigonometric functions, and multiplying the resulting central angle by Earth's radius. The approach supports output in kilometers, miles, and nautical miles, and can be extended with input validation and TypeScript support. As a practical example, the formula returns approximately 3,935 km between New York City and Los Angeles.

Researchers Propose LSTM-Based Smartwatch System to Detect Infections Before Symptoms

A technical framework published on DEV Community outlines how Long Short-Term Memory (LSTM) neural networks can be deployed on wearable devices to predict illness onset by monitoring resting heart rate. The system analyzes seven days of heart rate data to establish a personal baseline and flags deviations greater than two standard deviations as potential infection alerts. To fit within the hardware constraints of smartwatches, the model is compressed using post-training quantization, converting 32-bit floats to 8-bit integers via TensorFlow Lite. All inference runs locally on the device using TensorFlow Lite Micro, meaning health data never leaves the wearable. The guide recommends publicly available datasets such as PMData or MyHeart Counts for training and targets deployment on ARM Cortex-M processors.

Why Genetic Algorithms Can Overffit Trading Strategies — and How to Prevent It

Genetic algorithms (GAs) are powerful tools for optimizing trading strategy parameters, but are prone to overfitting when applied naively to backtests. The core risk lies in fitness function misspecification — rewarding raw returns instead of risk-adjusted metrics like Sharpe ratio, consistency across time periods, and drawdown limits. To prevent overfitting, practitioners should use walk-forward testing, evolving parameters on in-sample data and validating on out-of-sample windows the algorithm never trained on. A final held-out data vault, never touched during development, serves as the ultimate check on whether a discovered edge is real or illusory. Additional safeguards include decaying mutation rates, elitism, diversity pressure, and ensuring the backtest and live trading systems share identical code paths.
