I am not sure Dark Pools (DP) have been created to avoid "market manipulation". They have been created by firms because they found an advantage to create them (see Market Microstructure in Practice, L and Laruelle Eds.). The main reasons have been: spare market fees, for DP created by brokers (like UBS MTF); spare market impact, for block pools (like ...

Latency (both line latency and latency internal to the exchanges), adverse selection, market impact (yes, even you have market impact), etc, are all based on assumptions. These assumptions are educated guesses at best, but more often terrible models are used (you always get filled at at mid!) and ...

backtrader (https://github.com/mementum/backtrader) can do 1 and 3 and is in the process of getting 2 ironed out. A live data feed from IB will make it into the next release (due in the next few days) and it will then be down to mapping of orders. On the project page you can see a list of other similar (some more, some less) python projects and may prove to ...

It is typically FPGA that will host marketfeed handler (see NOVASPARKS website, or ACCELLIZE) ; analytics computations ; risk computation (see ULLINK solution for instance). For more, this generic article is not that bad: Introducing ...

Your source is not particularly clear about why what they're doing is a Z-score. To give some background, what they're doing is calculating $$\frac{R-\mu_{R}}{\sigma_{R}}$$ where R is the number of runs and the mean and standard deviation are of the number of runs. It's really more of a test statistic than a Z-score per se. The denominator in their formula ...

I think the best choice for technical analysis with node is node-talib, a wrapper around TA-Lib. We're using it for some projects and it works ok so far. Here's a list of the indicators you get out of the box: AD Chaikin A/D Line ADOSC Chaikin A/D Oscillator ADX Average Directional Movement Index ADXR ...
