Hi,

To add to what figmentofmyass said, You cannot ignore future volumes anymore. the liquidation mechanism introduced by leverage trading is one of the greatest liquidity pool in the market right now.
1- Following those area of high liquidity can be highly profitable
2- Historically, those areas have been a "magnet". The price always tended towards them.

Though it must not be forgotten that most derivative platforms only have an index of the Bitcoin price, calculated by weighting different spot exchanges spot-prices (Kraken, Bitstamp...)
