quantifying the spike11 Aug 2020 18:59
It is interesting to look at the recent spike in factual terms. It began Wednesday morning 5th Aug when SP broke 0.6p first thing and rapidly broke 0.7p at 11:37.
Main part of the spike was for the rest of Wednesday, with SP consistently above 0.7p.
It first dipped back below 0.7p at 09:32 next morning Thursday. For the rest of Thursday it hoevered around 0.7p, crossing the line up and down several times. Next morning, Friday, SP opened decisively below 0.7p and has drifted down consistently since then.
So we have 4 periods of interest (data from XLON's spiffy new API):
(A) quick ramp up, 0.6p to 0.7p (5th Aug, 08:00 - 11:37) 166 trades, 389k gbp
(B) spike, above 0.7p (5th Aug 11:37 to 6th Aug 09:32) 337 trades, 646k gbp
(C) hovering ... could go either way (6th Aug 09:32 to end of day) 136 trades, 297k gbp
(D) post-spike, below 0.7p and falling (7th Aug to now) 343 trades 561k gbp
Note that Zak Mir's trader tip was on 5th Aug. It seems likely that the substantial portion of the people who got spiked were traders following Zak's tip. (I hope that they were not people following GK's very opaque "tip").
It also seems likely that most of these traders will now be bailing out. To get a feeling for what might actually be happening, it's worth looking again at the volume numbers with time periods attached:
Ramping up, 389k gbp in 4 hours
Spike, 646k gbp in 6 hours
Hovering, 297k gbp in 7 hours
Drifting down, 561k gbp in 3 days, at time of writing (end of Tuesday)
