Exit bid-ask spread filter amount

The Exit bid-ask spread filter amount sets a maximum allowed bid-ask spread for exit orders (closing a long or covering a short) as a fixed amount in the symbol’s quote currency (for example 0.02 is 0.02 in that currency—often $0.02 on a USD-quoted stock). If the current spread 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.

Select $ above the input to use this mode, or None to disable the filter. Exit bid-ask spread filter percent is the alternate percent cap; only one unit is active on the strategy or subscription at a time.

Spread is evaluated from live bid and ask on the quote used for that exit. In dollar mode, TradersPost compares the absolute bid–ask width (|ask − bid|) against your configured maximum. This feature requires market data (quotes) from your broker; if the broker does not support quotes, the filter is not applied (exits are not blocked for spread).

The entry bid-ask spread filters are separate: see Entry bid-ask spread filter amount and Entry bid-ask spread filter percent.

Webhook bidAskSpreadFilter (exit)

For action: "exit" (and equivalent exit signals), the webhook may send bidAskSpreadFilter (dollar amount in the quote currency) to cap spread for that exit. Sending both bidAskSpreadFilter and bidAskSpreadFilterPercent in the same payload is rejected.

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 for Allow signal exit bid-ask spread filter is enabled

When those conditions apply and the payload includes bidAskSpreadFilter, the dollar amount is the exit cap and the configured percent is ignored for that signal. When they apply and the payload includes bidAskSpreadFilterPercent instead, the percent is the exit cap and the configured dollar amount is ignored. When they apply but the payload omits both keys, the configured Exit bid-ask spread filter amount or Exit bid-ask spread filter percent on the strategy or subscription is used (whichever mode is selected there).

If neither Allow signal overrides nor Allow signal override for Allow signal exit bid-ask spread filter is enabled, both keys in the webhook are ignored for exit planning and only the strategy or subscription’s configured exit spread filter applies.

Example webhook payloads

Exit using only the configured exit spread filter:

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

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

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