I will consider it. Somehow I would have to collect accurate STEEM price data. It is difficult to do that since exchanges have locked STEEM up in the past and marooned that STEEM on the exchange. That caused prices to fluctuate wildly which is not an accurate representation of actual price. Most coin pricing apps have reflected that as real. Overall I would expect that pricing overlay would present a false narrative as market pressure is king. One would assume by looking at one of those charts that there may be some correlation while the real factor is ignored (all the coins have gone down in price).
