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

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

@Sammy800 great job like always, thank you some much!!!


@samer800 quick question i just saw for long entry, do you think the short may be good? thanks

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

Thanks as always @samer800 . Does this repaint?

Following up @samer800 👋😁

The developer doesn't always know? I didn't know that but noted. I'll watch it Tuesday and see (y)

Following up @samer800 👋😁

mod note:
There is nothing in the code that indicates any repainting behavior.
Except: obviously, the current candle will update every tick (repaint) until it closes.
This is true with all charts, all platforms, whether you put any indicators on your chart.
Because it is not possible to know what the current candle close is going to be until it actually closes.

FYI, here is how to know if an indicator on the forum repaints:
  1. If an indicator in this forum contains apparent repainting logic, the thread will be labeled with the "repaints" prefix.
  2. There's always a chance that something might have been missed. Thus, if you observe any repainting activity on CLOSED candles, it's recommended that you make a post.
  3. When expressing your concerns, please provide detailed information about the specific behavior you're witnessing.
Also, including a chart link is always beneficial. The behavior you're seeing could be triggered by a different indicator.

If you're unsure of how to share chart links:
How to create a shared chart link:
https://usethinkscript.com/threads/how-to-share-a-chart-in-thinkorswim.14221/

@IPA
I have no idea what BlackCat, the developer knows or doesn't know. That would be a conversation that you would need to have over on Tradingview.
@samer800 is a scripter of great renown, who has been unceasingly generous in converting these scripts, but he is not the author of them.

Not seeing how you would short with this strategy.
Can you share what your idea would be?
Agree, if possible, would be nice to have a short colored candle as signal for banker entry short, possibly magenta, on upper chart when bar color = yes; which then also corresponds with lower indicator producing magenta vertical bar for short trade.

Basically just the opposite of what we have now in blue for banker entry but for a short in different color to visualize between long and short which depicts alignment on both upper chart candle and lower indicator.

I added short option but not sure how accurate, need further testing.

Hi Samer, thanks for giving that a go. The visualization is great with the magenta for bankerexit.

I need to study and compare changes. One thing I noticed right away is the bankerentry signals (cyan) changed and gave more signals, not sure why.

I compared code line by line between the original and new version and seems like the bankerentry code remains unchanged in new version, however the way it functions changed and gave more & different signals even though it seems the only code added overall was for bankerexit as shown below. I didnt see any bankerentry changes.

row 45 def bankerExit = Crosses(fundtrend, bullbearline, CrossingDirection.BELOW) and bullbearline > 75;
row 55 AddChart(high = if bankerExit then 100 else na, low = 0 , open = 100, close = 0,
row 56 type = ChartType.CANDLE, growcolor = Color.DARK_RED);
row 86 if bankerExit then Color.MAGENTA else

I probably dont't fully understand the orignal design concept but thought multi-directional signals visualizing the entry and exit would add value.

Thanks you for your efforts!

you are correct, the change on related to high and low. change the below and will be same like old code.
def lol = Lowest(low, 34);
def hoh = Highest(high, 34);

@samer800 please can you update the file, i dont know how to or where to put this line here to the original code. thank you in advance

Thanks for that I made the change and everything looks good. Appreciate all your coding!

Pleased note I change some color coding but all the logic and function is for the latest version with bankerexit:

Very intriguing!

What's the primary change in this latest update? Does it have a "Short" signal?
I realize this is a lower study; however, on the original post there appears to be a cyan colored confirmation candle on the top chart. Is that from another study? I am not getting that on my chart.

Thank you
