Most of these read your trade journal. The more you log, the more they can tell you —
several of them say nothing at all until there is enough history to be honest about, which is
deliberate. A win rate from five trades is noise, and a tool that presents it as a finding is
worse than one that stays quiet.
Risk & Sizing
Eight tools that run entirely on your own trade history. No market data, no API key, nothing to configure — they work the moment your journal has trades in it.
Position Sizer
How many shares, given your account size, stop and risk tolerance. Warns when a symbol is already over-weighted, and shows your record with the name before you commit.
ATR Stop Planner
Where to put the stop, based on how much the stock actually moves. Fetches ATR from daily bars so you don't have to look it up.
R-Multiple Planner
Plan entry, stop and targets in R. Then shows how much of your planned R you historically capture — usually the most uncomfortable number in the journal.
Expectancy Matrix
Does your edge survive the arithmetic? Plots your real win rate and reward:risk on the grid, and names which lever is closer to fixing a negative expectancy.
Kelly Calculator
Position size from your own win rate — with error bars. Shows what Kelly says at the pessimistic end of your sample, which is the number that survives being wrong.
Risk Comfort
What you say about risk, next to what your journal shows you did. Holding period and loss size on winners versus losers.
Volatility Guardrails
Long-term allocation: cash buffer, rebalance bands, and a glidepath that steps risk down as drawdown deepens.
Tax-Loss Harvester
Loss candidates, with wash-sale flags checked ±30 days against your journal. Flags where to look — it can never tell you that you're clear.
Options
For sizing and pricing an options trade you have already chosen. Options Hub picks the strategy; these two do the arithmetic on the real contract.
Research
Fundamentals-based tools for the long-term side. These read Finnhub, so they need an API key saved under Account.
Intrinsic Value
Three valuations side by side — DCF, Graham and dividend discount — with a margin-of-safety buy price for each.
DCF Analyzer
Discounted cash flow with a sensitivity grid. Pulls free cash flow, shares and net debt automatically; growth and WACC stay yours.
Moat Finder
Screens for the financial footprint a durable advantage leaves: sustained return on capital, fat margins, low leverage.
Dividend Screener
Filter dividend payers on yield, payout ratio, leverage and interest coverage.
Dividend Tracker
Income, yield on cost and a twelve-month forecast across your holdings. Imports open positions from your journal.
