e.g. bid 0.655 offer 0.66 , changed to 0.65 and 0.655 respectively , and it revert back again and vice versa.
What time did u observe this?
If it is 8.30-8.59am or 5-5.05pm, it is par for the course. Part of market open or close routines. Orders are aggregated as they are entered (or removed) but not executed yet until the final minute. Hence the cycling of bid/offer levels.
