Yeah that would make sense, like if the signals were known to have certain faults / false signals etc. But from reading these posts the guy said that it involves no discretion, and that they were basically working on automating the function.
Sorry for slow reply. Took myself out of the running for the dealing role in the end as I got offered and accepted a role in structured products structuring at a French IB. I started this role a couple of weeks ago so have been too busy to come on here. The whole interview process for this role was initiated and finished in less than a couple weeks and started well after the Harmonic interview process which was dragging out a long time.
