What is AgX?
The Mayer's multiple (200 days moving average of the BTC/USD price) is known to be a good indicator of the BTC price evolution.
AgX aims to be a similar indicator regarding the STEEM/SBD ratio, in order for users to find the right moment to exchange their SBD for STEEM at the best possible rate.
When the blue line is at the top of the graph it's a historically good time to sell steem for SBD, and at the bottom of the graph a historically good time to sell sbd for steem.
