Indicator Go

============



Indicator is a Golang module that provides a rich set of technical analysis indicators, strategies, and a framework for backtesting.



### Major improvements in v2:



-	**Enhanced Code Quality:** A complete rewrite was undertaken to achieve and maintain at least 90% code coverage.

-	**Improved Testability:** Each indicator and strategy have dedicated test data in CSV format for easier validation.

-	**Streamlined Data Handling:** The library was rewritten to operate on data streams (Go channels) for both inputs and outputs. If you prefer using slices, helper functions like [helper.SliceToChan](helper/README.md#func-slicetochan) and [helper.ChanToSlice](helper/README.md#func-chantoslice) are available. Alternatively, you can still use the [v1 version](https://github.com/cinar/indicator/tree/v1).

-	**Configurable Indicators and Strategies:** All indicators and strategies were designed to be fully configurable with no preset values.

-	**Generics Support:** The library leverages Golang generics to support various numeric data formats.



I also have a TypeScript version of this module now at [Indicator TS](https://github.com/cinar/indicatorts).

-   [Stop Loss Strategy](strategy/decorator/README.md#type-stoplossstrategy)



🗃 Repositories

--------------



Repository serves as a centralized storage and retrieval location for [asset snapshots](asset/README.md#type-snapshot).



The following [repository implementations](asset/README.md#type-repository) are provided.



-	[File System Repository](asset/README.md#type-filesystemrepository)

-	[In Memory Repository](asset/README.md#type-inmemoryrepository)

-	[Tiingo Repository](asset/README.md#type-tiingorepository)

-	[Alpaca Markets Repository](https://github.com/cinar/indicatoralpaca)



The [Sync function]() facilitates the synchronization of assets between designated source and target repositories by employing multi-worker concurrency for enhanced efficiency. This function serves the purpose of procuring the most recent snapshots from remote repositories and seamlessly transferring them to local repositories, such as file system repositories.



The `indicator-sync` command line tool also offers the capability of synchronizing data between the Tiingo Repository and the File System Repository. To illustrate its usage, consider the following example command:



```bash

$ indicator-sync \

    -source-name tiingo \

    -source-config $TIINGO_KEY \

    -target-name filesystem \

    -target-config /home/user/assets \

    -days 30

```



This command effectively retrieves the most recent snapshots for assets residing within the `/home/user/assets` directory from the Tiingo Repository. In the event that the local asset file is devoid of content, it automatically extends its reach to synchronize 30 days' worth of snapshots, ensuring a comprehensive and up-to-date repository.



⏳ Backtesting

--------------



The [Backtest functionality](strategy/README.md#type-backtest), using the [Outcome](strategy/README.md#func-outcome), rigorously evaluates the potential performance of the specified strategies applied to a defined set of assets. It generates comprehensive visual representations for each strategy-asset pairing.



```go

backtest := strategy.NewBacktest(repository, outputDir)

backtest.Names = append(backtest.Names, "brk-b")

backtest.Strategies = append(backtest.Strategies, trend.NewApoStrategy())



err = backtest.Run()

if err != nil {

	t.Fatal(err)

}

```



The `indicator-backtest` command line tool empowers users to conduct comprehensive backtesting of assets residing within a specified repository. This capability encompasses the application of all currently recognized strategies, culminating in the generation of detailed reports within a designated output directory.



```bash

$ indicator-backtest \

    -source-name filesystem \

    -source-config /home/user/assets \

    -output /home/user/reports \

    -workers 1

```
