Ok, so what to do now depends on your risk profile. You could dump in your cash now but that's very risk in this bear environment, this could just be a temporary pull back.
I'm sitting on cash to invest so I am looking for candles closing on a lower low followed by a higher high. Typically, but not always, the longer the timeframe you see this formation on the lower the risk.
1) Higher risk - 1 hour time frame
Look for a pull back and close with a higher low followed by a higher high. e.g. next hour pull back to around 6.3k and then the next hour or two a high that is greater than the bar that just ended ($6690).
2) Medium risk - as per above but on the 4 hour timeframe
The other option is to watch out for a double bottom with a strong volume based rejection. i.e. we retest the 6k low but bounce back quickly and aggressively. I'd want to see this with at least 3-6 hours (the more the better) separating them.
