Do you think its a good idea to add an extra line for the history of the feed (or Call Price)? That would allow traders to have a price history showing even if the bitAsset market has traded thinly and lacks a smooth line (or in cases like Shenzhen, any line at all), which means another application is required to be used in conjunction to get this data. Traders like to see the price history and movement, because it affects their speculations.
What are the windows for the MACD lines? Could these be specified or labelled?
