Towards AASTRA V2

Introduction

We have skimmed through the drawbacks of AASTRA V1 on our previous blog.
This research and implementation is in continuation with our strategies; utilising concentrated liquidity to earn non speculative yield. Strategists, here's a walk-through of our current backtester for community assessment and testing.

The following repository contains python scripts that are used by Brahma Finance to simulate and backtest strategies on concentrated amm's like uniswap v3. The repo is structured as follows:

data/ folder contains the csv files related to swap data of ETH-USDC 0.3% pool and average gas cost per block.

notebooks/ folder contains the jupyter notebook files used for simulation and backtesting the put selling strategy.

Coming to python files:

1. strategy_state.py base code for strategy, conducting either back-testing for put selling or range selection strategies (run_put_strategy function and passing in historical swap data)
2. big_query.py contains all functions for downloading the swap data from block chain etl
3. transformers.py contains all the transformation functions used calculating metrics on swap data.
4. univ3_funcs.py a modified python implementation of Uniswap v3's liquidity math built by JNP.

Backtesting

The new back tester has its main parts forked from active-strategy-framework by GammaStrategies. The main difference is that the data is downloaded in programmatic way from block chain etl and back testing is done on block by block basis.

In order to run the backtest for sample strategy provided :

• backtest.ipynb runs the rolling strategy with two lp positions.
• rolling_strategy.py contains the main code for rolling put selling strategy.

TO DO

The current backtester doesn't incorporate the following features, we are currently working to optimise this in the next version. Updates will include developments on:

1. Swap Costs
2. Gas Costs
3. Improving the running time of the backtest
4. Metrics Integration
5. HODL factor based on Prof.Lambert's work
6. Cleaning up the previous backtest code base.

TLDR;

Currently upgrading the backtester for V2 and buidling upon future strategies for AASTRA.
