This screen shot displays the songbird monitor and the two providers in question submitting near identical pricing data outside of the band for a significant period of time.

Flare evidence:

As displayed there is a gap in the submissions between these two providers. On the left is BestFtso, on the right is AilandFlare.

The final submission on the left, before the gap, co-insides with when BestFtso was chilled the first time they were implicated. On the right of the gap is the first time we see AilandFlare submitting on Flare. One can make their own conclusions when observing this chart, but along with the evidence displayed on songbird, it shows at the very least these two providers are heavily intertwined.

Yikes, havent seen anything like that before.
Knowing that both run ML this can only happen with a combination of 2 things.
Using same feeds to get data and same algorithm that crashed at the same time and both kept the same coefficients.
If they used different data feeds or different ML algorithm this could never happen.
Looking forward to their reply.


Thanks for the extra info @alexdupre … this proves collusion without any question.


Based on the evidence presented above FTSO London supports this proposal to go forward.
