You don't need to be Nostradamus to predict a fall 15 minutes in advance
Directly, memorize the following information:
1) On the verge of a fall
Dark red == whales
Medium red == sharks
Light red == sardines
2) If the red area is larger than the green one, supply is greater than demand, so the price tends to fall.
3) Confirm using another indicator, for example the chart below, which shows an abrupt outflow of money, most likely because whales are selling.
