If you're tracking R-multiples in a spreadsheet and wondering why your equity curve is flat, SignalDeck was built for you. Not another trade log — a performance laboratory.
Doesn't matter — your R makes up for it
Optimal risk per trade
Win rate is a vanity metric. A 40% win rate with 3R average winners prints money. A 70% win rate with 0.5R average winners bleeds capital. SignalDeck normalizes everything by risk so you can see what actually matters — your expectancy per unit of risk, not just your batting average.
SQN scoring tells you if your system is statistically tradable. Kelly Criterion sizes your positions based on YOUR data, not a textbook formula. Monte Carlo simulation shows you the worst drawdown you should expect at 95% confidence.
Every competitor lets you tag a trade as "win" or "loss" and move on. We built a structured 5-step diagnostic that forces you to understand WHY. Was it a good win (process + profit) or a bad win (gambling + luck)? Was it a good loss (process + stop hit) or a bad loss (broken rules)?
Setup Diagnosis. Management Diagnosis. Final Verdict. Training Gap identification. Mentor Feedback. When you review 50 Post Mortems and see that 80% of your bad losses come from "Chased Extension / Bad Location" — that changes your trading forever.
Total Friction Cost: $0.16/share
Limit Alpha: +$0.22 saved by limit orders
Most traders have no idea what their fills actually cost them. We measure entry slippage (the gap between your intended price and actual fill), exit slippage (how much your stop moved on execution), and limit alpha (the price improvement you gain from limit orders vs market orders).
Over 100 trades, a $0.15 average slippage on a $50 stock is $15/trade in invisible friction. On 100 shares, that's $1,500 you never see leave — until your equity curve tells the story. We make it visible.
Markets change. Strategies that worked in a trending market break in a range. SignalDeck tracks your rolling 20-trade win rate, expectancy momentum (last 20 trades vs all-time average), and win rate velocity. When these diverge, you know your edge is eroding — before the account tells you.
Combined with our equity curve and cumulative R-curve, you have a cockpit-level view of your system's health. Not retrospective analysis — real-time diagnostics.
You track R-multiples — or you want to start. You know win rate alone doesn't tell you if your system works.
You're past the "tips and alerts" phase. You want to diagnose your own execution, not follow someone else's.
You're currently using a spreadsheet, or you're paying $30+/month for a journal that treats R-value as an afterthought. You want a tool built by a trader, for traders, with a release cycle that actually listens.
