SignalDeck is a professional-grade trading journal and strategy backtester for serious retail traders. Unlike general-purpose trading journals, SignalDeck uses R-Multiple (risk-normalized return) as the organizing principle for every metric — equity curves, expectancy, SQN scoring, Kelly Criterion position sizing, and Post Mortem reviews all flow from a single risk framework. It supports stocks, forex, CFD, crypto, and futures (ES/NQ/CL/GC) natively. The built-in strategy backtester includes Walk-Forward Analysis for overfitting detection, 1,000-path Monte Carlo simulation for worst-case drawdown modeling, and grid-search parameter optimization — a combination no other trading journal offers. SignalDeck is currently in beta and free to use.
SignalDeck exposes the gap between your strategy and your execution. Professional-grade analytics for traders who are done with spreadsheets and ready to treat this like a craft.
Walk-Forward Analysis · 1,000-path Monte Carlo · Grid-Search Optimizer · R-Multiple — the only trading journal with all four.

Money lost to hesitation and poor fills. This isn't the market's fault - it's yours.
Are you actually improving, or just riding a lucky variance streak?
HIGH
Correlation detected between "FOMO" tags and 2R+ drawdowns.
The System Quality Number - Tells you if your system is statistically tradable or just a fluke. Anything above 2.0 is a professional edge.
0.84R
For every dollar you risk, this is what your system returns - on average. This is the only number that actually matters.
$1,150
Profit left on the table from missed signals. Your strategy found the entries - you just didn't take them.
Built for traders who journal — or want to start. If you're tracking R-multiples in a spreadsheet, paying $30+/month for a journal that treats R-value as an afterthought, or you just know your edge is real but can't prove it yet — SignalDeck was built for you.
Every closed trade gets a mandatory 5-step forensic review. No shortcuts. No skipped trades. This is where amateurs become professionals — one trade at a time.
Stop managing a spreadsheet. Start running a performance lab with the same metrics professional traders use to prove their edge is real.
Automated scanning of 5,000+ stocks at 6am EST. Work with our team to implement your custom strategy and identify signals before the bell.
We snapshot RSI, MACD, and SMA values at the exact minute of your entry. Review every trade with the full technical context of the market at that second.
Seamless integration for individual position review. Jump from forensic metrics directly to a live chart to visualize your edge where you actually trade.
Don't start from zero. Our team handles the heavy lifting of uploading your messy broker history so your analytics are dangerous on day one.
Built for speed. Navigate audits, filter campaigns, and tag positions with minimal mouse clicks. Optimized for the high-frequency workflow.
More than buy/sell orders. Export full forensic datasets to CSV for LLM auditing or ongoing Machine Learning simulation and strategy tweaking.
Connect your MT4 or MT5 account via MetaApi and trades import automatically — fills, P&L, symbol, volume, and price, with no manual entry of execution data. Your live account balance syncs in real time, so Kelly Criterion sizing and fixed-R risk calculations always reflect your actual current equity — not a stale number you entered last month. Stop loss is added in the post-trade review step to complete R-Multiple tracking.

Monte Carlo simulation models your worst-case drawdown across 1,000 paths. Grid-search optimizer finds your best parameters. Then link the backtest to your journal strategy and compare theory against your actual execution — all in the same platform.
Explore the strategy backtesterFutures are now first-class instruments. ES, NQ, CL, and GC are tracked with tick-aligned P&L math (not shares, not pips — contracts × ticks × tick value), CME Globex session monitoring, and front-month contract search. The contract spec is fetched automatically so you just enter price and contract count. Prop firm futures challenges on Apex Trader Funding, Topstep, and TradaFi are fully supported.
Explore futures journalingMost trading journals lead with win rate as the headline metric. It's also the most misleading number in trading — a 40% win rate can be highly profitable while a 75% win rate bleeds your account, depending on your reward-to-risk. SignalDeck tracks Risk Leakage, SQN, and R-value expectancy to show you whether your edge is statistically real. Know your breaking point before the market finds it.
Your journal is a proprietary training set. Export clean, forensic-grade CSVs formatted for LLMs or Monte Carlo simulations. Built for the lab - not just the ledger.
Explore trading analyticsThe Accountability Calendar is your trading accountability layer — it turns your month into a visual audit trail. Every trading day shows your P&L, journal entries, and post-mortem completion at a glance, so you can spot patterns in your discipline before they cost you. No more hiding bad weeks from yourself.
Step away from standard charting alerts and bring the notifications into your journal ecosystem. Set unlimited triggers on the basics like break-even and stop levels - or behavioral caps like max trades per day and exceeding your ideal dollar risk. It’s about being tapped on the shoulder when you’re breaking your own rules before the drawdown gets expensive.

Run any of 16 built-in strategies against up to 5 years of historical data. Walk-Forward Analysis catches overfitting before you go live. Monte Carlo simulation runs 1,000 paths to model your worst-case drawdown at the 5th percentile. Then link the backtest directly to your journal strategy — and see exactly where your live execution diverges from theory.
Prop firm challenges cost $200–$1,000+. Before you register, check whether your current trading run would actually pass — profit target, max drawdown, daily loss limit, minimum trading days, and the consistency rule.

Win rate is the most misleading metric in trading. A 40% win rate can be highly profitable while a 75% win rate bleeds your account — depending on how much you make versus how much you risk per trade.
R-Multiple normalizes every trade outcome against the risk you took. Risk $100 and make $250 — that's 2.5R. Every strategy, session, pair, and instrument is now directly comparable. SignalDeck builds SQN, Kelly Criterion, expectancy, and your entire equity curve on top of R — not raw dollars.

Most journals only see trades after they close. SignalDeck watches your open positions in real time and fires price, stop-level, and break-even alerts inside the journal — so you don't need a separate charting tab open to enforce your own rules.
Futures alerts (ES, NQ, CL, GC) are gated to CME Globex hours so you never get spurious pings when the market is closed. No competitor offers position-attached live alerts inside the journal.
