I could argue that the stoploss be taken a little higher but I believe in cutting loosing trades early. The chart looks easily explainable even to a lay man; Since the basic in trading is "selling the roof and buying the floor". We are currently at a known high pricemark that we can see price has been rejecting over time and can say the recent bull rally to the tradinal high is the retest before a sell off to 49K region.
