Seismic Graph
The seismic graph was calculated as following:
- Subtract close price from previous close price for each day
- Normalize this data by dividing by the average of both prices (0.5 * (previous_close_price+ close_price))
- Divide by the volume of that day

I haven’t seen this before so just want to make sure I’m reading this right. Not sure what ‘seismic’ is in this case but I’m assuming it is percentage price change per volume? Is that right? If so this is a pretty impressive visualization highlighting the effect of reduced liquidity in the stock.
