Scalping

Scalping and liquidity hunting

Some of the strongest records on any perp venue belong to traders operating on horizons measured in seconds. Those same records are the least useful to a copy system, and it is worth being explicit about why.

In short

Scalpers and liquidity hunters extract small edges from order-flow imbalance, liquidation cascades and short-lived dislocations. Their per-trade edge is smaller than the latency and slippage cost a follower incurs, so the archetype rarely survives replication intact — however impressive the leader's own record is.

What the strategy actually does

Liquidity hunting targets predictable forced flow: clusters of stops and liquidation levels that must transact regardless of price. The trader positions ahead of that flow and exits into it, often within seconds.

The edge per trade is tiny and the trade count is enormous. Profitability depends entirely on execution quality — queue position, latency, and the ability to cancel and re-enter faster than the market moves.

  • Thousands of fills, minuscule average result per fill.
  • Edge is execution, not opinion.
  • Any delay between leader and follower consumes a large share of the per-trade margin.
  • Fee sensitivity is extreme relative to slower archetypes.

Why replication degrades it

A mirrored order is by definition later than the leader's. For a strategy whose entire edge is measured in basis points captured over seconds, that delay is not a rounding error — it can be the whole edge.

The honest conclusion is that a great scalper is often a poor allocation target. Scoring can identify them accurately and still exclude or heavily de-weight them, because the score describes the leader's results, not the follower's.

What is used instead

Archetypes with holding periods long enough that a few seconds of delay is immaterial receive the bulk of allocation. That is a deliberate trade of headline score for realized fidelity.

Past performance is not indicative of future results. Perpetual futures are leveraged instruments and carry a substantial risk of loss, including the loss of your entire position.

Questions

Frequently asked

Are scalpers excluded entirely?

Not by rule, but the shorter the holding period the more heavily replication cost weighs against them, and the most extreme cases are not viable copy targets.

Is this about the platform being slow?

No. Any copy system is downstream of the leader by construction. The gap can be minimised, never eliminated.

Could a scalper still be worth copying?

If their holding period is minutes rather than seconds and their per-trade edge is comfortably larger than realistic slippage, yes.

Does liquidation hunting harm other users?

It transacts against forced flow that would occur regardless. It is a normal feature of leveraged markets, not a defect of the venue.

How is holding period measured?

From the public fill record: the elapsed time between the fills that open and close each position.
