Kline package overview

When loading data for the kline, it can come from two sources: candles or trades. In the config they are represented as common.CandleStr or common.TradeStr respectively.

Candle data represents the opening, closing, highest, lowest prices of a given timespan (interval) along with the volume (amount traded) during that same period. You can read more about candles here. This data is utilised throughout the GoCryptoTrader Backtester in order to make informed strategic decisions.

Trade data represents the raw trading data on an exchange. Every buy or sell action for the given currency. When trading data is used for the GoCryptoTrader Backtester, it is converted into candle data at the interval you specify. This allows for custom candle intervals not provided by an exchange's API and thus has a greater amount of flexibility in backtesting strategies.
