Black lines show relative (most objective) trend, while Red lines are fixed (subjective) trend lines. IMO it is highly improbable to see BTC under 10.5 k. Any retracement near this area is your best chance to buy a bargain. Personally I don't expect BTC going under 10.7 k.
Context is bullish also. We might see a small accumulation phase. So I don't expect this to happen until elections. B U T... be prepared.
