Reading the spread flicker before a move
Just before a notable move, the spread sometimes flickers, alternating between narrow and wide in quick succession. Liquidity providers adjust quotes nervously as they sense incoming flow or news, and the displayed spread reflects their hesitation.
For scalpers, it is a short-lived cue. If the spread flickers while price is flat, a move may be coming, although the direction is unknown. If an existing trade is open, the flicker suggests a higher chance of slippage on the exit.
Detecting it requires fine data: spreads sampled at every tick. A simple count of spread changes over a 5-second window, compared to a baseline, can serve as an indicator.
The signal is not reliable on its own. Many flickers lead to nothing. But combined with other conditions, such as proximity to a key level or a scheduled event, it can improve timing and caution.
Try logging spread change counts and compare them against subsequent volatility to see whether a pattern exists in the data.
Does the spread flicker precede movement on the pair being traded, according to the logs?
