Exit bid-ask spread filter

The Exit bid-ask spread filter sets a maximum allowed bid-ask spread for exit orders (closing a long or covering a short). If the current spread for the symbol exceeds this cap when an exit is planned, the exit order is rejected to reduce the chance of fills in illiquid or very wide-spread conditions.

The value is a positive dollar amount (for example 0.02 means $0.02). Leave blank to disable the exit filter.

Spread is evaluated from live bid and ask on the quote used for that exit. This feature requires market data (quotes) from your broker; if the broker does not support quotes, the filter is not applied.

The entry bid-ask spread filter is separate: setting one does not set the other, and the exit filter does not apply when planning an entry.

Webhook bidAskSpreadFilter (exit)

For action: "exit" (and equivalent exit signals), the webhook may send bidAskSpreadFilter to cap spread for that exit.

The effective exit cap is taken from the webhook when either:

• Allow signal overrides is enabled on the strategy or subscription, or
• Allow signal override is enabled for Exit bid-ask spread filter

If signal values are allowed for this field and the payload includes bidAskSpreadFilter, that amount is the exit cap. If signal values are allowed but the payload omits bidAskSpreadFilter, the configured Exit bid-ask spread filter in the strategy or subscription is used.

If neither Allow signal overrides nor Allow signal override for Exit bid-ask spread filter is enabled, bidAskSpreadFilter in the webhook is ignored for exit planning and only the configured Exit bid-ask spread filter applies.

Example webhook payloads

Exit using only the strategy’s configured exit spread filter:

{
    "ticker": "AAPL",
    "action": "exit"
}

Exit with a per-signal cap (requires Allow signal overrides and/or Allow signal override for Exit bid-ask spread filter as above):

{
    "ticker": "AAPL",
    "action": "exit",
    "bidAskSpreadFilter": 0.02
}
