Period, scope & variants

The three controls that decide what the catalog shows: the backtest period every metric is computed over, the scope lens, and the strategy-variant selector.

Before touching a single filter, decide what you're measuring: over which window (Period), from which pool (Scope), and across which strategy families (Strategy Variants).

Period

Period Configuration panel with the period dropdown

Every metric in the catalog — MAR, CAGR, drawdown, win rate — is computed over the selected period. Changing it recomputes the whole table, which is why the same strategy can rank very differently on a 4-week versus a 52-week window.

There are two kinds of period, and they are measured differently:

KindOptionsHow it's measured
Rolling windows1W (5 trading days) · 2W (10) · 4W (20) · 8W (40) · 12W (60) · 24W (120) · 26W (130) · 52W (260)The most recent N trading days, anchored to the latest data point — the current partial month is included.
Calendar periods1M · 3M · 6M · 12M · 24M (completed months) · Total (full history)The N most recently completed calendar months — the current partial month is excluded.

The default is 26W (130 trading days, roughly half a year). Because the two kinds are measured differently, similar spans (say 12W and 3M) can produce different numbers — that's expected, not a bug.

Data through

The period banner showing the active period and the data-through date

The Data through pill shows the most recent trading day reflected in what you're seeing — a date that is both backtested and in the cache the app reads. New backtest data lands roughly once a week, so a date a few days back is normal, not stale.

Scope

Scope lens and Strategy Variants selector

The scope is a lens over one unified strategy pool:

  • All (default) — database strategies and your own imports together.
  • Database — the curated database only.
  • Mine — only strategies you've uploaded via Import. They become first-class strategies and mix freely with the database in the Builder.

Strategy Variants

The variants dropdown filters by strategy family. All variants are derived from one backtest per width / stop / premium / entry-time combination — each variant is a different selection over those same atomic spreads, which is why the family results reconcile exactly.

VariantWhat it is
MEIC Both SidesMultiple-Entry Iron Condor: every entry sells a put spread AND a call spread, no trend gate.
MEIC Put-only / Call-onlyThe two sides of that same iron condor as standalone strategies — Put-only + Call-only = Both Sides exactly.
METF 20-40 / 5-40 / 5-20 (Both)Multiple-Entry Trend Following: each entry sells a put OR a call spread, picked by that day's EMA trend. The EMA pair only changes how entries split between puts and calls.
METF Put-only / Call-only (per EMA pair)Just the put-side (uptrend) or call-side (downtrend) entries of the gated METF.
Ratio 1P:2C / 1C:2POne big spread (the width/premium shown) against two smaller opposite-side spreads at half the premium each — 1P:2C is a big put with two calls, 1C:2P the mirror.

The row's family badge (MEIC, METF, 1C:2P, OWN, …) tells you at a glance which family a strategy belongs to; the row itself encodes width, stop loss, premium and entry time — covered in Metrics & columns.
