• Technical Indicators: Popular indicators including EMA, RSI, SuperTrend, ADX, ATR, and more
• Alternative Candles: Heikin-Ashi and Renko chart implementations
• Easy to Use: Clean, intuitive API with comprehensive documentation
• Type Safety: Full type hints and validation support

Installation

pip install tradelab

For Development

git clone https://github.com/husainchhil/TradeLab.git
cd TradeLab
pip install -e .

Quick Start

import pandas as pd
from tradelab.indicators import EMA, RSI, SuperTrend, ATR, ADX
from tradelab.candles import RENKO, HEIKINASHI

# Sample OHLCV data
data = pd.DataFrame({
    'open': [100, 101, 102, 103, 104],
    'high': [105, 106, 107, 108, 109],
    'low': [99, 100, 101, 102, 103],
    'close': [102, 103, 104, 105, 106],
    'volume': [1000, 1100, 1200, 1300, 1400]
})

# Technical Indicators
ema_20 = EMA(data['close'], period=20)
rsi_14 = RSI(data['close'], period=14)
atr_14 = ATR(data['high'], data['low'], data['close'], period=14)
supertrend = SUPERTREND(data['high'], data['low'], data['close'])

# Alternative Candles
heikin_ashi = HEIKINASHI(data)
renko_chart = RENKO(data, brick_size=1.0, mode='wicks')

Available Indicators

Trend Indicators

• EMA - Exponential Moving Average
• SuperTrend - Trend-following indicator with dynamic support/resistance
• Normalized T3 - Triple exponential moving average with volume factor

Momentum Indicators

• RSI - Relative Strength Index (0-100 oscillator)
• ADX - Average Directional Index (trend strength)

Volatility Indicators

• ATR - Average True Range (market volatility)

Comparative Analysis

• Relative Strength - Compare performance between two securities

Alternative Candle Types

Heikin-Ashi

Smoothed candlesticks that filter market noise and highlight trends.

from tradelab.candles import HEIKINASHI

ha_candles = HEIKINASHI(ohlcv_data)

Renko Charts

Price-based charts that ignore time and focus on price movements.

from tradelab.candles import RENKO

renko_bricks = RENKO(ohlcv_data, brick_size=1.0, mode='wicks')

Data Utilities

OHLCV Resampling

TradeLab includes a powerful resampling function for converting OHLCV data to different timeframes.

from tradelab.utils import resample_ohlcv

# Resample to 1-hour bars starting at 9:15 AM
hourly_data = resample_ohlcv(data, freq="1H", anchor="09:15:00")

# Resample to 15-minute bars
intraday_data = resample_ohlcv(data, freq="15T", anchor="09:30:00")

# Resample to weekly bars starting on Monday
weekly_data = resample_ohlcv(data, freq="1W", anchor="MON")

Features:

• Flexible Timeframes: Support for any pandas frequency string (1H, 30T, 15min, 5S, 1W, etc.)
• Custom Anchoring: Align bars to specific times (intraday) or days (weekly)
• Proper OHLCV Aggregation: Open=first, High=max, Low=min, Close=last, Volume=sum
• Data Validation: Automatic column validation and cleaning

Performance

TradeLab uses Cython for performance-critical calculations, providing significant speed improvements over pure Python implementations:

• 2-10x faster than equivalent pandas/numpy operations
• Memory efficient with optimized data structures
• Type-safe with compile-time optimizations
