Momentum is a conserved quantity meaning that the total momentum of any closed system (one not affected by external forces) cannot change. (Wikipedia). Note that financial markets are not closed systems. Any multiplier/constant/ratio employed could be made useless when new external forces come into play (who may have targets of their own, not corresponding to any existing targets).
Yet, it is intriguing to recall Noether's (first) theorem which states that any differentiable symmetry of the action of a physical system has a corresponding conservation law.
It may seem that something similar to conservation law is being observed with triggers.
If a physical experiment has the same outcome regardless of place or time, then its Lagrangian is symmetric under continuous translations in space and time; by Noether's theorem, these symmetries account for the conservation laws of linear momentum and energy within this system, respectively. The problem begins when you are to explain why the system conserves the information about various independent "momenta" in the same direction or in the opposite directions and the "momenta" are independent, they do not interfere with each other, they do not sum up or swallow each other.
Triggers are not momenta. Triggers, on the other hand, resemble solitons (3 properties ascribed to solitons):
1. They are of permanent form (stable);
2. They are localised within a region;
3. They can interact with other solitons, and emerge from the collision
unchanged, except for a phase shift.
In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed. Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium.

Solitons can help explain certain odd behavior of the market (like why farther targets can be reached quicker than nearer targets - see the animation under Collision between two solitons traveling in the same direction - while nearer targets are marked after a retracement).
