Methods

price

price(__namedParameters: { symbols: string[] }): Promise<{ ok: true; value: T }>
Each symbol's latest USD price, however old, keyed by the symbol as held. null for a symbol never quoted: the caller shows its amount and leaves it out of a USD total, never counting it as zero.
Parameters
- __namedParameters: { symbols: string[] }
Returns Promise<{ ok: true; value: T }>
Inherited from AssetPriceService.price
- Defined in packages/account-sync-services/src/AssetPriceService.ts:45

record

record(
    __namedParameters: {
        prices: { asOf: Instant; symbol: string; usd: BigNumber }[];
    },
): Promise<{ ok: true; value: { recorded: number } }>
Stores quotes. A quote already stored for its (symbol, quote time) is left as it is, so a retried run writes nothing twice.
Parameters
- __namedParameters: { prices: { asOf: Instant; symbol: string; usd: BigNumber }[] }
Returns Promise<{ ok: true; value: { recorded: number } }>
- Defined in packages/account-sync-services/src/AssetPriceAdminService.ts:54

searchHeldSymbols

searchHeldSymbols(): Promise<{ ok: true; value: string[] }>
Every symbol some ledger account has a balance row in, read as getHoldings reads holdings, less the fixed-price ones.

Returns Promise<{ ok: true; value: string[] }>
- Defined in packages/account-sync-services/src/AssetPriceAdminService.ts:28

series

series(
__namedParameters: { from: Instant; symbol: string; to: Instant },
): Promise<
{ ok: true; value: { items: { asOf: Instant; usd: BigNumber }[] } },
>
One symbol's recorded quotes between from and to inclusive, oldest first. A fixed-price symbol has none.
Parameters
- __namedParameters: { from: Instant; symbol: string; to: Instant }
Returns Promise<{ ok: true; value: { items: { asOf: Instant; usd: BigNumber }[] } }>
Inherited from AssetPriceService.series
- Defined in packages/account-sync-services/src/AssetPriceService.ts:88

value

value(
__namedParameters: { holdings: WalletAssetHolding[] },
): Promise<{ ok: true; value: HoldingsValuation }>
Holdings marked to market, for display; an unpriced asset stays out of the total.
Parameters
- __namedParameters: { holdings: WalletAssetHolding[] }
Returns Promise<{ ok: true; value: HoldingsValuation }>
