altcoin index oscillator

Compare alt coins to the "altcoin index", an average of a selection of alt coins.
Above zero means the coin you are viewing is worth more than the index, indicating the possibility of overbought.
Below zero indicating the opposite, a possibility of oversold.
Press the cog icon to select which alt coins you want included in the index.

The coins in the index are ALTBTC, meaning their value against BTC . Due to this the indicator is useless when viewing BTC only charts.
