Using bookmap liquidity map and cumulative delta, quote in XBTUSD@MEX, I programmed market making in python and C# for Bitmex and live broadcast in  https://www.youtube.com/watch?v=bhBXNCQKuq4   (Kindly note that URL address has been updated after rebooting recording computer) If this topic is out o...

Is time delay in Bitmex due to websocket? In receving of future and option data, data is received through UDP in multicasting with end point. In DMA(direct market access), I have no experience of time delay or missing events. In polling, cumulative volume data is sacrificed through sampling. In cryp...

Time delay is detected by Bookmap after 15 minutes(4:45 am Jan.2, 2020). Heatmap is redrawn correctly. But from practical viewpoints of traders, suboptimal solution showing polling is better than frozen and redrawn after 15 minutes. Profit and loss is far more important than optimality. However if ...

Subscribe/Receive has drawback in delay as in current bookmap trade(time and sales) for several minutes in overload condition. In practical purpose, I choose to subsample trade data and orderbook by switching polling methods in overload. O verload condition is triggered by longer delay computed fro...

Bookmap shows upport/resistance by high liquidity(thick heatmap) at NOW, not conjectured from previous price volume profile. If large green volume dot in upward direction pierces through thick heatmap of resistance, knowledge of resistance vs breakout BEFORE actual price movement is IMPORTANT. By co...

Freezing of XBTUSD@MEX at 12:01 PM Jan 2,2020. Operation of time sales resumed with 3 mins delay. After 10 mins., bookmap screens disappear(flash) and refresh by itself with normal operation of zero delay. Question 1: What is cause of freezing and delay? Perhaps same as my C# market making codes for...

I run market making using order book and trade data in bitmex. The overload and unexpected problems from Bitmex exchange require human intervention . I would ...

As emphasized in https://bookmap.com/wiki/Liquidity_tracker,
Liquidity flux and Volume flux are not delayed indicators like moving average or volume weighted price
of trailing sum, but is real time.
