Definition
A member's publicly known equity or option purchase dollars divided by the sum of both, across all disclosed tickers. Event versions enter only when public. Unclassified instruments are excluded. purchaseScope defaults to AllPurchases for historical flow. RemainingLots sums surviving original purchase costs after reported full sales and exercises, excluding unresolved ticker buckets. Unknown partial quantities retain their estimate. Neither setting is current market value or verified holdings.
Parameters
Bioguide member ID, instrument (Equity or Option), amount basis (LowerBound, Midpoint, UpperBound), purchase scope (AllPurchases or RemainingLots)
Output range: 0 to 100 percent; zero before a qualifying purchase
Example condition
`PoliticalPurchaseShare("P000197", "Option", "Midpoint")`Use in a strategy
Add this indicator to a strategy condition, choose its supported parameters and compare the output with the threshold required by your rule. Preserve the same interval and lookback when comparing backtests.
After saving the condition, inspect its asset, interval, lookback and comparison operator against the parameters above. If no trades occur, check whether the condition ever became true and whether the requested input data exists for that period. A missing input is not a zero-valued signal. An indicator produces an input to a rule. It does not establish future returns, and data availability can differ across assets and periods.
