Comparing ALTPERP with BTCPERP gives a somewhat similar chart as the BTC.D chart. At daily timeframes, it seems as if altcoins have botomed against their BTC pairing (looking at momentum and strength indicators). I am expecting a small altcoin season as of right now that will last till early (4-9th) November. After that, Bitcoin will surge and make a blow-off top, resulting in a large altcoin outbreak that is suggested by this symmetrical triangle.
