This chart shows bitcoin vs US Dollar on a Daily time frame. Notice the 4 colored lines. These are custom scripts that show good levels to buy and sell the instrument.
A close below the Blue line could open the door for a trip to the Red line, which is currently around $8500. That level would be bearish and I would consider shorting it there.
