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 when Allow signal override next to the quantity settings (or the global Allow signal overrides) is enabled. When enabled, TradersPost will take the quantity value from the incoming webhook signal and multiply it by the number you provide here.

The one exception is action=resize, which always reads the quantity it is sent, so the multiplier always applies to it. The multiplier scales the target, not the difference: a follower on 2 who received buy 2 holds 4, and a resize 3 gives them a target of 6, so they grow from 4 to 6 while the author grows from 2 to 3. That keeps a scaled follower in proportion instead of resetting them to the author's literal size.

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 x 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 Allow fractional quantity is enabled).
• If the calculated final quantity is below 1 and fractional quantities are not allowed, TradersPost forces the quantity up to 1 instead of rounding down.
• If fractional quantities are allowed, sub-1 values are kept (subject to broker decimal limits).

Tip

If you don't want to use the quantity from the signal, leave Allow signal override next to the quantity settings disabled (and the global Allow signal overrides off) and configure your own quantity calculation method instead.
