For the past couple of evenings, I’ve been trying demo trades with 5-second expirations, and I still haven’t figured out where the strategy ends and mere randomness begins. I’m only looking at simple movements after a sharp impulse, but the result varies significantly even on the same section of the chart. When I was looking for materials, I often came across the query “binary options strategy 5 seconds,” although many explanations boil down to a couple of general phrases without any proper examples. I’m deliberately not rushing to switch to a real account; first I want to separately test at least several dozen identical entries. Has anyone actually tested such a short expiration period on a demo account? What did you focus on more: the direction of the candle, the level, or the speed of the movement?
