—Overview
Tradebot is an automated trading platform for crypto, listed securities and derivatives. A Symfony 7.4 backoffice declares the bots, their strategies and their risk limits; a Node.js runtime executes them against Bitvavo, Kraken, Coinbase, Binance and Saxo. Every strategy climbs the same ladder — backtest, dry-run, then a tiered go-live — every amount is an exact decimal, and every decision lands in a journal.
02The front
What people see.
The backoffice writes the desired state, the runtime reports the actual one. Each change of configuration becomes an immutable revision, validated against a JSON Schema contract on both sides before a single order can follow it.
Dry-run first,
live by design
Dry-run and backtests share one execution engine, so a simulated fill costs what a real one would. Live trading stays locked until a strategy has survived the validation protocol, then opens in tiers — 10, 25, 50, then 100 % of its allocation — with a global kill switch one click away.
—Screens
Scroll sideways
No strategy trades real money until it has survived the protocol — and the protocol has rejected every one so far.
