Database trading Data Storage Formats
TLDR; ArticDB looks to be the best current option.
CSV - Simplest, slowest, largest and no data types can lead to type errors when loading.
SQL Database - typically transactional row store (OLTP), slow for analysis (OLAP), difficult to shard and parallelize workloads over clusters.

technical trading Technical analysis is a trading strategy used by investors to identify new investment possibilities. To anticipate future price movements of stocks or other assets, for example, past price and volume data is studied and shown on graphic charts, where trends, patterns, and technical indicators can be identified.

This is the same method practiced by economists and meteorologists: looking to the past for insight into the future.

option chain in tradingAn option chain lists all option contracts, including put and call option for given security. However, several traders focus on net change,' 'bid,' 'last price,' and 'ask,' columns to assess current market conditions. Option chain is also called the option matrix.
How does an option chain work? An option chain displays available call and put options for a specific underlying asset, with their strike prices, premiums, and open interest. It provides a snapshot of market sentiment and potential price movements.
How To Use EMA The **Exponential Moving Average (EMA)** helps traders in several ways by providing insights into price trends and momentum. Here’s how EMA benefits traders:
### 1. **Trend Identification**:
- EMA gives more weight to recent price data, making it responsive to the latest price movements.
- It helps traders identify the current trend (uptrend or downtrend) more quickly compared to Simple Moving Average (SMA).
### 2. **Support and Resistance Levels**:
- EMAs often act as dynamic support and resistance levels. Traders observe how prices react around these EMAs to gauge market sentiment.
### 3. **Entry and Exit Signals**:
- Traders use crossovers of EMAs (like a short-term EMA crossing above a long-term EMA) to generate buy or sell signals.
- A common strategy is the **Golden Cross** (short-term EMA crossing above long-term EMA, signaling a buy) and the **Death Cross** (short-term EMA crossing below long-term EMA, signaling a sell).
### 4. **Momentum Measurement**:
- The slope of the EMA line indicates the momentum of the price. A steep slope suggests strong momentum, while a flat EMA indicates weakening momentum.
### 5. **Filter False Signals**:
- By smoothing out price data, EMA helps reduce noise and false signals, making it easier for traders to focus on the underlying trend.
### 6. **Complement Other Indicators**:
- EMA is often used alongside other technical indicators like RSI, MACD, and Bollinger Bands to enhance trading strategies and confirm signals.

Arctic is built upon Mongo to make it even more helpful for those who work with market data, as Arctic supports pandas dataframes and NumPy arrays by default
What Is AVWAP And How to Use Properly Anchored Volume Weighted Average Price (Anchored VWAP) is a technical analysis tool used by traders to determine the average price of a security, weighted by volume, from a specific starting point in time. Unlike the traditional VWAP, which resets at the start of each trading session, Anchored VWAP allows traders to select any point on a price chart as the starting anchor for the calculation. This flexibility makes it useful for analyzing the price action around significant events, such as earnings releases, breakouts, or market corrections.
### How Anchored VWAP is Calculated:
1. **Select an Anchor Point:** This could be a specific date, the start of a significant event, or any relevant point on the chart.
2. **Calculate VWAP from that Point:** From the anchor point, the VWAP is calculated by taking the sum of the product of the price and volume for each period, divided by the total volume, up to the current time.
### Formula:
\
Where:
- \( P_i \) = price at the ith period
- \( V_i \) = volume at the ith period
- \( n \) = total number of periods since the anchor point
### Uses of Anchored VWAP:
- **Support and Resistance Levels:** It helps identify potential support or resistance levels based on the average price since the chosen anchor point.
- **Trend Analysis:** It provides insights into the market trend by showing the average price participants have paid since a significant event.
- **Entry and Exit Points:** Traders use it to find optimal entry or exit points by comparing the current price to the Anchored VWAP.
Anchored VWAP is widely used by both retail and institutional traders for making more informed trading decisions.
Technical trading Technical traders analyze price charts to attempt to predict price movement. The two primary variables for technical analysis are the time frames considered and the particular technical indicators that a trader chooses to utilize.

ADX: The Trend Strength Indicator
Average Directional Movement Index
The Average Directional Movement Index, or ADX, is a popular trend indicator designed to measure the moving average of price range expansion values. Developed by Welles Wilder, it's one part of the Directional Movement System which aims to measure price movements and their strength.
What is the ADX? The average directional movement index is calculated to reflect the expansion, or contraction, of the price range of a security over a period of time. The traditional setting for the ADX indicator is 14 time periods, but analysts have commonly used the ADX with settings as low as 7 or as high as 30.

Some traders follow something called the "10 a.m. rule." The stock market opens for trading at 9:30 a.m., and there's often a lot of trading between 9:30 a.m. and 10 a.m. Traders that follow the 10 a.m. rule think a stock's price trajectory is relatively set for the day by the end of that half-hour.
