Momentum burst is the shortest-lived strategy in the set. It is not trying to hold a trend; it is trying to be present for a brief acceleration and gone before the acceleration stops. The exit condition does more work than the entry condition, which is unusual and is the reason the strategy is hard to run.

This covers what acceleration means mechanically, why the entry has to cross the spread, and how the same trade turns into a different and worse one if it is held.

Detecting Acceleration, Not Direction

The distinction the strategy rests on is between price moving and price accelerating. A market drifting steadily upward has direction but no acceleration; one that suddenly travels several times its recent per-interval distance has both. Only the second is the setup.

Acceleration is measured by comparing recent movement against the pair's own baseline — the rate over the last few intervals against its typical rate. When that ratio spikes, the strategy treats it as an impulse worth joining.

Entry is immediate and marketable. The strategy then holds only while the impulse persists, and exits on the first of three conditions: a quick target, the momentum measure fading back toward baseline, or a stop. The fade condition is the important one, because it is what makes this a burst strategy rather than a trend strategy.

One implementation detail from this system is worth recording. The strategy previously required a volume confirmation alongside the price move, and that gate silently suppressed most of its signals — the price impulses it was built for frequently arrived before the volume did. Removing the gate is what made it fire on genuine price momentum. A filter that never lets a strategy act is indistinguishable from the strategy not working, and the two are diagnosed very differently.

Impulsive, Not Orderly

What this needs is impulsiveness: a market that occasionally moves sharply rather than smoothly. News arriving, a large participant transacting quickly, a cascade through resting orders — the cause is irrelevant to the mechanism, but the shape is not.

An orderly market offers nothing. If a pair advances the same modest distance every interval, the acceleration measure never spikes and the strategy stays flat. Like the breakout strategy, it spends most of its time dormant, and that dormancy is correct rather than a malfunction.

It also needs enough liquidity that a marketable order fills near the price that triggered it. This is in tension with the setup itself: the sharpest impulses often occur when the book is thinnest, which is exactly when crossing costs the most. The strategy is drawn to the conditions that penalise its own execution.

Crossing, and Crossing Again

There is no resting version of this entry. By the time acceleration is measurable the move is already happening, and an order resting at a better price will not be reached by a market travelling away from it. So the entry crosses and pays the taker fee.

The exit usually crosses too. A momentum fade is detected rather than predicted, and acting on it means taking whatever is available now. Both legs at the taker rate makes this the most expensive round-trip in the set, alongside the breakout strategy.

Slippage compounds the problem. Crossing during an impulse means the book is moving underneath the order, so the fill can be meaningfully worse than the trigger price. The faster the impulse the strategy correctly identified, the worse the price it gets for identifying it — the cost scales with the quality of the signal.

Together these set a demanding floor. A burst has to be large enough to cover two crossings plus slippage on both, and many bursts that are real and correctly detected are simply too small to clear it.

Holding a Burst Turns It Into Something Else

The characteristic failure is not a wrong entry but a late exit. A burst that has stopped accelerating and is held anyway becomes a position in an ordinary market, taken at an above-average price with none of the structure a trend strategy would have put around it — no established direction, no reference level, no near stop. The trade has quietly changed identity into one that was never designed.

This is why the fade exit carries more weight than the entry. Being right about acceleration and wrong about when it ends produces a loss on a correct signal, and the strategy has no way to recover from a hold except by exiting worse.

The second failure is the exhaustion move. Some of the sharpest accelerations are the end of a move rather than the start of one — a final flush as the last participants transact. These are indistinguishable from continuations while they happen, and the strategy joins them at the least favourable point available.

The third is mechanical: a burst can complete inside the interval the strategy measures on. If the acceleration begins and finishes between two observations, the strategy enters after it is over. Shortening the interval reduces this and increases the number of trivial moves that register as impulses, so it trades one failure mode against another rather than removing either.

Momentum burst is the strategy where the exit is the design. Joining an impulse is comparatively easy to specify; leaving before it stops is what the whole construction is for, and holding past that point converts it into a different trade nobody planned.
