TT Score

Momentum Ignition

Momentum Ignition

Momentum ignition trading patterns attempt to create directional price movement and then to capitalize on the result. Typically, momentum ignition is identified by a series of aggressive orders submitted in a short time span in an attempt to trigger resting stop orders, which then cause pre-placed orders to be executed at a profit by the ignited price movement.

Scoring methodology

To detect potential momentum ignition, TT Score searches for specific patterns of fill activity by the same trader who submitted the aggressive orders. It looks for traders who place multiple orders that immediately lift offers or hit bids within a short time frame (called aggressive orders). For each of these aggressive orders, TT Score identifies fill prices for orders executed at multiple price levels and whether the changing fill prices trend in same side as the aggressive orders. Finally, it determines whether a fill was received too quickly on the opposite side of the market from the aggressive orders.

Score interpretation

The score assigned is based on a sliding scale between 0-100, based on the relationship between the aggressive order fill quantities and the profit-taking order fill quantities.

Scorecard metrics

The Scorecard Metrics section measures the following statistics related to momentum ignition:

  • Ignitier Price Levels: Number of price levels at which the aggressive orders were filled. The sequence of price levels at which fills occur correspond to the movement in market price (i.e. Buy orders at increasing price levels that contribute to an increase in market price).
  • Ignites (Vol): Fill volume for the “aggressive” orders (bids that immediately lift offers or offers that immediately lift bids within) within a time frame.
  • Opp. Side (Vol): Volume of fills received on the opposite side of the market from the aggressive order within a time frame.

Identifying momentum ignition

When investigating Momentum Ignition clusters with TT Score, you should focus on the:

  • Number of distinct price levels used by aggressive orders.
  • Quantity filled on the aggressive orders.
  • Quantify filled on the opposite, or profit-taking, orders.

For example, if the Igniter Price Levels and the Ignites (Vol) metrics display large values, this indicates that the trader may have been attempting to ignite a price movement in a particular direction (buy or sell) in order to mislead other market participants or to create an artificial price. The Opp. Side (Vol) is a good indicator of whether or not the trader received advantageous fills on orders opposite the igniter orders that the trader would not have otherwise received without intentionally or recklessly sparking the price movement.

The order audit trail data on the Statistics Scorecard can then be used to verify all of the order information and the timing of the activity that was identified as potential Momentum Ignition.

The activity can then also be replayed on the Market Ladder Replay tool and viewed on the Macro Chart.
