my strategy depends on time frame with gann angles while i see there is very important times to let us indicate the btc trend while his circle is almost finished " may be some days more but any way i expect the next important time after round 4 am and the second one will be on 7/02/2018 if the time come and the price still the same trend " then...
i think max point will be round 12980 + or - 1% in this point he will go under the 270 degree so we can seell at 12900 and wait to buy again
