Signal quantity multiplier

The Signal Quantity Multiplier allows you to scale the quantity provided in a trade signal up or down by a fixed decimal value.

This multiplier is applied only if the “Use signal quantity” option is enabled. When enabled, TradersPost will take the quantity value from the incoming webhook signal and multiply it by the number you provide here.

Example

Incoming webhook signal:

{
  "ticker": "MNQ",
  "action": "buy",
  "orderType": "market",
  "quantity": 2
}

Signal quantity multiplier: 2.5

Result: TradersPost will submit a market order for 5 contracts (2 × 2.5).

Use Cases

• You want to follow a signal provider’s trades, but your account is larger or smaller than theirs.
• You want to scale all trade sizes from a strategy, regardless of what quantity it sends.
• You want to reduce exposure (e.g. use 0.5 to take half-size positions).

Notes

• Supports decimal values like 0.1, 1.5, 2, 10, etc.
• Can be used to scale down as well as up.
• Works with both whole and fractional quantities (if your broker supports fractional trading and "Use fractional quantity" is enabled).
• If the calculated final quantity results in a decimal and your broker does not support fractional shares/contracts, the value will be rounded down.

Tip

If you don't want to use the quantity from the signal, you can leave "Use signal quantity" disabled and configure your own quantity calculation method instead.
