Time Windows

The time window selector filters almost every metric in the app. Understanding how it works prevents misreading your numbers.


Available windows

Window Date range
YTD January 1 of the current year to the latest transaction date
Last 7 Days Rolling 7 calendar days
Last Month Rolling 30 calendar days
Last 3 Months Rolling 90 calendar days
Half Year Rolling 182 calendar days
1 Year Rolling 365 calendar days
All Time Full CSV history

The window selector appears at the top-right corner of the Derivatives Performance, Discipline & Patterns, and Portfolio P/L tabs. Changing it updates all tabs simultaneously.


What the window affects

Metric Windowed?
Realized P&L ✅ Yes
Realized ROR ✅ Yes (uses windowed P&L)
Capital Efficiency ✅ Yes (uses windowed P&L and window days)
Div + Interest ✅ Yes
Closed trades table ✅ Yes — filtered by close date
Derivatives Performance scorecard ✅ Yes
Discipline & Patterns charts ✅ Yes
Capital Deployed ❌ No — always shows current open positions
Account Age ❌ No — always shows full history
Campaign cards ❌ No — campaigns always show full lifetime

Capital Efficiency and short windows

Capital Efficiency is an annualised return figure:

Cap Efficiency = (Window P&L ÷ Capital Deployed ÷ Window Days) × 365 × 100

Short windows (Last 7 Days, Last Month, Last 3 Months) will produce dramatically higher or lower annualised rates than your true long-run figure. A great week can show 200%+ annualised. A bad week can show deeply negative. This is mathematically correct but should be interpreted with caution.

The All Time window gives the most reliable Capital Efficiency reading.


Period comparison card

The Portfolio P/L tab shows a comparison between the current window and the prior equivalent period. For example, with Last Month selected, it compares the last 30 days against the 30 days before that, showing absolute and percentage deltas for each metric. This card is not shown when All Time is selected.


How filtering works

The window filters on the transaction date stored in the CSV (UTC). For options, this is the trade execution date. For equity sales, this is the settlement date as recorded by TastyTrade.

FIFO equity P&L in a window only includes sales whose execution date falls within the window. The cost basis for those sales is still calculated from the full history — a sale in the Last 7 Days window will correctly use a purchase cost from 6 months ago.
