Using the HR2 BTCUSD chart here we have the 12 EMA, 26 EMA, 100 EMA and 200 EMA. We notice that we are safe to trade while the 100 EMA is above the 200 EMA and they are slightingly moving upwards. You'll notice support continuing to be found around the 200 EMA. Notice that when the 12 EMA crosses the 26 EMA so long as the 100 EMA is above the 200 EMA we have an interesting opportunity for a long. Whereas when both the 12 EMA and 26 EMA begin to point towards the 100/200 EMAs we could consider exiting our position (especially if the 12/26/100 EMAs all begin curving and pointing towards the 200 EMA). So far this strategy has worked out fairly well, however, we don't want to get locked into a confirmation bias of "it will bounce from the HR2 200 EMA every time" and should use caution when entering from this lower level out of speculation.
