Advanced Analytics in Market Microstructure Analysis: Unlocking Hidden Insights

The field of market microstructure analysis is a crucial aspect of quantitative finance as it helps to understand how market participants interact with each other and how these interactions impact prices. Advanced analytics has become an increasingly important tool in market microstructure analysis, allowing researchers to uncover hidden insights and make better-informed decisions.

Market Microstructure

In this article, we will explore several key topics in the use of advanced analytics in market microstructure analysis, including order book analysis, transaction cost analysis, volatility modelling, market manipulation detection, latency analysis, market impact analysis, and liquidity analysis.

Order Book Analysis: Uncovering Patterns of Order Flow

Advanced analytics can analyze the order book, a record of all the buy and sell orders in a market. This can include identifying order flow patterns, such as order clustering and momentum ignition, and understanding how these patterns impact prices.

For example, using machine learning techniques to detect high-frequency traders' behaviour and its impact on the order book can help us to understand how their actions affect the market.

Transaction Cost Analysis: Minimizing Costs of Execution

Advanced analytics can analyze the costs of executing trades, such as bid-ask spreads and market impact. This can include identifying factors influencing transaction costs, such as order size, and developing models to predict costs.

For example, using simulation and optimization techniques to minimize transaction costs for a high-frequency trading strategy can help traders to execute trades more efficiently.

Volatility Modeling: Capturing Dynamics of Prices

Advanced analytics can be used to model the volatility of prices, which can be helpful in option pricing and risk management. This can include using techniques such as GARCH models and stochastic volatility models to capture the volatility of different assets and its dynamics over time.

For example, using an artificial neural network to predict volatility using high-frequency financial data can give traders an edge in predicting market movements.

Market Manipulation Detection: Identifying Suspicious Patterns

Advanced analytics can detect instances of market manipulation, such as insider trading, wash trading, and spoofing. This can include using network analysis and anomaly detection techniques to identify suspicious trading patterns.

For example, using machine learning to detect manipulative behaviour by identifying abnormal order cancellation patterns can help regulators to detect and prevent market manipulation.

Latency Analysis: Reducing Delays in Market Data

Advanced analytics can be used to analyze the speed of market data and orders, known as latency. This can include identifying sources of latency, such as network delays and software limitations, and developing strategies to minimize latency.?

For example, network and data analysis to identify and reduce latency in a high-frequency trading system can help traders make faster and more accurate decisions.

Market Impact Analysis: Understanding the Impact of Trades

Advanced analytics can be used to analyze the impact of trades on prices, also known as market impact. This can include identifying factors influencing market impact, such as order size and arrival time, and developing models to predict market impact.?

For example, using data mining to identify the relationship between the trade size and its impact on the market price can help traders make better-informed decisions about trade size.

Liquidity Analysis: Measuring the Ease of Trade

Advanced analytics can be used to analyze the liquidity of markets, which measures how easily assets can be bought or sold. This can include identifying factors that influence liquidity, such as trading volume and bid-ask spreads, and developing models to predict

Python Code for INFY Insider, Bulk and Block Trades:

Code that extracts historical bulk, block, and insider trades data for INFY in the last 5 years, retrieves historical prices of INFY in the last 5 years, calculates the next month's last date, merges the data, calculates the impact score for each trade, groups the data by client, and then calculates the average impact score for each client, sorted by the average impact score:

from nsepy import get_histor

from datetime import date, timedelta

import pandas as pd

import numpy as np

?

# get historical bulk, block, and insider trades data for INFY

infy_trades = get_history(symbol='INFY', start=date.today() - timedelta(days=365*5), end=date.today(),

??????????????????? index=False, group_by='day', security_type='EQ',

??????????????????? bulk_deals=True, block_deals=True, insider_trades=True)


# get historical prices for INFY

infy_prices = get_history(symbol='INFY', start=date.today() - timedelta(days=365*5), end=date.today(),

?????????????????? index=False, group_by='day', security_type='EQ')        

#merging the data

infy_data = pd.merge(infy_trades, infy_prices, on=['Date','Symbol','Series','Prev Close','Open','High','Low','Last','Close','VWAP','Volume','Turnover','Trades','Deliverable Volume','%Deliverble'], how='left')        

#calculating next month last date

infy_data['Next_month_last_date'] = infy_data['Date'] + pd.offsets.MonthEnd()        

#merging the data with next month's last date

infy_data = pd.merge(infy_data, infy_prices[['Date','Close']], left_on='Next_month_last_date', right_on='Date', how='left')        

#Renaming the column

infy_data = infy_data.rename(columns={'Close':'Next_month_close'})        

#calculating impact score

infy_data['impact_score'] = infy_data['Quantity']*np.abs(infy_data['Next_month_close'] - infy_data['Close'])
?

# group by client and calculate average impact score

infy_avg_impact = infy_data.groupby('Client').mean()['impact_score'].sort_values(ascending=False)


# display top 10 clients by average impact score

print(infy_avg_impact.head(10))y        

This code extracts historical bulk, block, and insider trades data for INFY in the last 5 years using the nsepy library and retrieves historical prices of INFY in the last 5 years. Then it merges the data of trades and prices so that we can use the close prices of INFY after the trades were made. Next, it calculates the next month's last date using the pandas.offsets.MonthEnd() function. Then it merges the data with the next month's last date, it renames the column, and then it calculates the impact score for each trade using the formula (Quantum of Transaction value) * (absolute price change in next 1 month after the trade date). The data is then grouped by the 'Client' column and the average impact score is calculated using the .mean() function. Finally, the data is sorted in descending order to show the top 10 clients by average impact score.
