Background
The large funds or banker fund are often referred to as Whale. Whale can have a significant impact on the price movements in various markets, especially in cryptocurrency . Therefore, how to monitor Whale trends is of great significance both in terms of fundamentals and technical aspects.
Function
L3 Banker Fund Flow Trend Oscillator can give you a model of complete banker fund flow operation in cycles. Although the script is not so complicated, it is comprehensive to disclose the price trend. That is the reason why I list this as Level 3. Each cycle of banker fund flow may have 5 steps in max as entry, increase position, decrease position, exit, and weak rebound for exit.
Key Signal
1. banker fund entry with blue candle
2. banker increase position with green candle
3. banker decrease position with white candle
4. banker fund exit/quit with red candle
5. banker fund weak rebound with pink candle
Pros and Cons
Pros:
1. Model banker fund behavior in complete cycles
2. Overbought and oversold can be directly observed due to oscillator nature
3. the transition points are clear for entry or exit
Cons:
1. Simple modelling, no further complex behaviors can be disclosed
2. trade by trend following the banker fund, it is still under the trend analysis prerequisite
