Just some musings about short interest.
First, @ihors3 was under reporting $TSLA short interest (32.62 vs 37.19 for 15 Oct 2019) [1]
Second, @ihors3 latest report is $TSLA short interest of 32.95 [2]
His new chart shows a spike up to the real short interest mid-month -- looks like it was inserted as an outlier without any smoothing. Unfortunately, that far back Market Watch only shows daily, but there was no noticeable change in close compared to prior/following days so it seems (relatively) unlikely that it was a weird spike on the 15th.
In terms of the utility of his data service (at least with respect to $TSLA) it looks useless* as it failed to accurately depict either the instantaneous amount of short interest (S3 "realtime" short interest) or the trend. On 15 Oct 2019 he was claiming that short interest had been in a steady decline starting August/September. A closer inspection of the charts shows that his current data diverged from the old starting with Oct 1st. Whereas before he had claimed a continued declined with a slight bump followed by a steep decline in short interest his revision shows an upward trend and where he had claimed the steep decline was instead a steep rise.
I'm not quite sure how the data is intended to be interpreted in support of short selling, but showing a steep decline in short interest when in fact there was an increase is not a minor error.
