#Hint: This Study displays the approximate current candle buy, sell, and total volume, (added an input if you would like to see premarket volume as well) for current time frame.  It also plots the approximate volume values for the total volume | average volume | approx sell volume | and aprox buy volume of timeframe under cursor.  Note: If the result returns N/A the high = close or low = close and time frame is a doji.  Choose your inputs to see premarket, total volume, and day market total volume.  There are also arrow indicators based on VWAP for enter and exit points.  The volume histogram always shows the dominant value in back and lowest volume in front.

#Hint: This Study displays the approximate current candle buy, sell, and total volume, with trend reversal warnings for current time frame.  (added an input if you would like to see premarket volume as well).  Works with both candle typse so choose the correct candle type in the input settings under Chart Type.  Furthermore, you must select your correct candle type, candle or HEIKIN_ASHI to get the most accurate approximation for buys and sales numbers.   The indicator also plots the approximate volume values for the total trading day volume | average volume | approx sell volume | and aprox buy volume of timeframe under cursor.  Note: If the result returns N/A the high = close or low = close and time frame is a doji.  Choose your inputs to see premarket, total volume, and day market total volume.  There are also arrow indicators based on VWAP for enter and exit points.  The volume histogram always shows the dominant value in back and lowest volume in front.  Use the VWAP agg time to adjust / dial in your VWAP for more volatile charts and better accuracy.

I will troubleshoot tomorrow. I just noticed myself. Will update soon
Click to expand...
The issue I had with the newer version is aggregationPeriod ........ if you go above the tf setting the entire study goes N/A.... a better approach is to have a toggle in which you would set how many aggregationPeriods to stay above the current chart timeframe no matter what it may be would be best implementation.

For example

input: ForwardLookingAggregation = { default "Current", "1 TF", "2 TF's", "3 TF's", "4 TF's", "5 TF's" };
