Technology articles
A trading platform is a piece of real-time software, and understanding it makes you a better-informed trader. The Technology series explains how live market data reaches your screen, why the price you click is not always the price you get, how automated and algorithmic trading work, how API keys should be handled, and how to secure a trading account properly.
The articles are written for traders rather than engineers: enough technical depth to understand what is going on, without assuming a programming background.
How live market data reaches your chart: ticks and quotes, how candles are built, polling versus WebSocket streaming, what latency is and why charts can differ.
How to protect a trading account: strong passwords and password managers, two-factor authentication, spotting phishing, and managing your sessions and devices.
What latency and slippage are, why orders fill at different prices than expected, how order type, liquidity and news affect fills, and how to reduce slippage.
What trading API keys are, how they differ from passwords, how to scope, store, rotate and revoke them safely, and the warning signs of a leaked key.
A beginner's guide to algorithmic trading: what algorithms do, common strategy types, the parts of an automated system, the real risks and how to start safely.
Foundations of chart reading and technical analysis, explained from first principles.
How to turn analysis into a repeatable plan — with risk management built in from the start.
Bitcoin, Ethereum and crypto trading explained: how the networks work, what moves their prices, and the risks they carry.
