This contracting triangle looks to be poised to break to the upside but given the higher time frame it is not the reasoninig for this intraday buying calls setup....instead, if you are measuring the 50% retracement from the longest wave of the triangle than you should see it is coming around the 130 level.......so this is both pivotal and support, and taking into consideration it is the last Friday or the week, and the last trading day of the month, chances to close above 130 are quite strong.....hence the buying calls idea
