Balances

client.balances reads current ledger balances and balance/equity history, and can stream live updates. Methods are authenticated and account-scoped (account / sub_account_id).

Balance component fields (trading, funding, reserved, available) are scaled integer decimal strings (ledger u128), not human floats. Values are already scaled integers on the wire. Format once with format_ledger_u128 (default scale 18) for display. Do not multiply by 1e18 again.

Methods

Method Summary
list Current balances for the account scope.
get_balance_history Columnar balance history over a range.
get_equity_history Columnar equity history over a range.
subscribe Stream private balance updates.

List

Python takes no required request object, optional scope only:

from polyester import format_ledger_u128

balances = await client.balances.list()
for b in balances.balances:
    print(
        b.asset_id,
        format_ledger_u128(b.available),
        format_ledger_u128(b.trading),
        format_ledger_u128(b.funding),
        format_ledger_u128(b.reserved),
    )

# Subaccount override
sub = await client.balances.list(account={"sub_account_id": "123"})

Held amounts come from each Asset's reserved balance in this result. Individual hold IDs and expiry times have no replacement. available already accounts for reservations; size new orders from it.

AssetBalance

Field Notes
asset_id Ledger asset id
trading / funding / reserved / available Scaled integer strings
trading_revision Orders trading/reserved/available
funding_revision Orders funding independently

Get balance history

history = await client.balances.get_balance_history(
    range="30d",  # 1d, 7d, 30d, 90d, 180d, 365d
    account_codes=None,  # optional list[int]
    ledger=0,
)
print(history.bucket, history.points, history.start_ts_sec, history.end_ts_sec)
for series in history.series:
    print(series.asset_id, series.account_code, len(series.balance_q))

Get equity history

equity = await client.balances.get_equity_history(
    range="90d",
    group_by="asset",  # or "account"
)
print(equity.quote_asset, equity.points)
for series in equity.series:
    print(series.asset_symbol or series.account_name, len(series.equity_q))

sub = await client.balances.subscribe(account_id=account_id)
async with sub:
    async for balance in sub:
        print(balance.asset_id, format_ledger_u128(balance.available))
        break
