The stop of 18200 has just been tapped but nothing has really changed in the grand picture of things. Ideally with Bitcoin and especially when trading such large magnitude trades the stop would be even further away than the text book hammer candlestick trade (below the local bottom of 17.5k).
We can wait for this weeks weekly candle to close and see if that forms another hammer. If so this would be a much more appealing trade as it would be near the mini-range (that has formed in the lower time frames on this support) low and the stop can be put below the local low.
This would mean that rather than being stopped out partly by "noise" (in this case when an asset bounces around erratically because of low volume), the stop would be triggered only on a decisive break of the support area.
To be clear I am still of the heavy bias that we have found a bottom but until a new trade signal develops on the larger time frames (weekly) we can't do much!
