About
SignalDeck is a trading journal and strategy backtester for prop firm traders and serious retail traders. It answers one question honestly: do you actually have an edge, and can you keep it on funded capital?
Most journals record what happened. SignalDeck is built to tell you whether it will keep happening. Every trade is normalised to R, the multiple of the risk you took, so expectancy, SQN, Kelly Criterion sizing, equity curves and Post Mortems all come from one risk framework. That makes a gold trade, a EUR/USD trade and an NQ trade comparable.
For prop firm traders, SignalDeck syncs a live MT5 balance and shows how much drawdown headroom is left before the next entry, not after the violation. For strategy work, the built-in backtester runs Walk-Forward Analysis, 1,000-path Monte Carlo simulation and grid-search optimization, then lets you compare a backtest against your live trades.
It supports stocks, forex, CFDs and indices, crypto and futures (ES, NQ, CL, GC) natively, imports trades from IBKR, cTrader, SnapTrade, CSV and MT4/MT5, and connects to Claude and ChatGPT through an MCP server.
SignalDeck has been in public beta since 2025. Features are shaped in our Discord with the traders using them, and every change ships in the release history.
We'd rather tell you a strategy is likely overfitted than show a flattering equity curve. Walk-Forward verdicts, Monte Carlo drawdown ranges and SQN exist to test an edge, not decorate it.
Every feature is free during beta. When billing launches, the plans are Free, Pro ($30/mo) and Elite ($50/mo). See plans.
We publish the methodology behind the numbers on the blog, offer free calculators, and support university investment clubs.
