Hi Paps,

Bookmap's Cumulative Volume Delta (CVD) start from when when you open Bookmap and connect to live data. It cannot add in previous data. However, there is a Reset button which allows you the reset the CVD and begin the accumulation of the delta anew. This can be very handy if you want to choose a specific point and study the delta at that point, without the dilution of previous data. I'd be happy to demo this for you if you like. Reach out to me at [email protected] and let me know. Also, please visit https://bookmap.com/strategies/ to read more about the Bookmap CVD and other API automated trading strategies and indicators. I will also post user case scenarios in this forum for using Bookmap's CVD.

regards,

Bruce

I tested the icebergs for 5 366 and they don't agree with the older version

See Screen Grab same data,
5 tested on replay, 4 on live and replay. Generally less icebergs show with 5.

Hi Johnl,

Thanks for your message.

Please note that the exchange doesn’t provide the indication of iceberg volume so the detection is done based on Bookmap algorithm that attempts to detect those iceberg places.

In 4.5 we improved the detection algorithm and the effect was fewer false detection of icebergs. We believe it is more accurate now because we developed the improvement based on raw exchange data.

Still, when Bookmap shows the iceberg it is not guarantied to be 100% accurate every time and you may find differences between the market data vendors that Bookmap supports. Main reason is that each data vendor transmit the data slightly differently and this affects the iceberg detection algorithm.

Best

Hi Sasa,

Here's a video that shows how to make the volume dots smaller, and how to use them. Hope it helps.

I just tried out my Bookmap demo for the first time and it is well put together. I couldn't make sense of the orderbook side but using the test data and following around the bid/ask line as well as the horizontal volume bars-- I was able to get in the flow of things and scalp in and out while kinda of getting an idea of how things work. What are the best videos to get a true understanding of how it work?
