Strategies package overview

Strategies are programmed instruction sets which act upon pricing data. After data has been loaded into the GoCryptoTrader, each tick is passed through your loaded strategy and is analysed in either the OnSignal function or the OnSignals function.

Creating strategies

The level customisation allowed in a strategy is extensive. They are required to be written in Golang. The strategy must adhere to the interface strategies.Handler by implementing the function signature OnSignal(d data.Handler, _ portfolio.Handler) (signal.Event, error). The data.Handler allows you to access the current pricing information as well as all previous intervals. You can use this to feed any Technical Analysis package to create strategies based on market movements such as RSI (see ./strategies/rsi/rsi.go). Strategies can also access the portfolio manager on signal(s) which allows analysis of existing holdings value, current orders and positions of other currencies in order to make complex decisions. When outputting the signal.Event, you are not dictating the price of an order, but rather signalling to the portfolio manager what ideally should occur. These options are to buy, sell or do nothing. Additional signals are to flag missing data, handled via checking d.HasDataAtTime(d.Latest().GetTime() to prevent any issues from occurring down the line. Additionally, you can utilise the AppendWhy() function to help understand what went into make a signalling decision when reviewing the results.

What does Simultaneous Signal Processing mean?

GoCryptoTrader Backtester config files may contain multiple ExchangeSettings which defined exchange, asset and currency pairs to iterate through a period of time.

If there are multiple entries to ExchangeSettings and SimultaneousProcessing is disabled, then each individual exchange, asset and currency pair candle event is evaluated individually and does not know about other exchange, asset and currency pair data events. It is a way to test a singular strategy against multiple assets simultaneously. But it isn't defined as Simultaneous Processing Simultaneous Signal Processing is a setting which allows multiple ExchangeSettings data events for a candle event to be considered simultaneously. This means that you can check if the price of BTC-USDT is 5% greater on Binance than it is on Kraken and choose to make signal a BUY event for Kraken and not Binance.

It allows for complex strategical decisions to be made when you consider the scope of the entire market at a given time, rather than in a vacuum when SimultaneousSignalProcessing is disabled.

Loading strategies

Each strategy has a unique name and is to be added to the function getStrategies() in order to be recognised.
