Backtesting
Backtesting is the practice of applying a trading strategy to historical market data to evaluate its potential performance. It allows traders to see how their logic would have fared in past market conditions, providing a proof of concept before risking real capital.
A successful backtest simulates real-world constraints like slippage, transaction fees, and liquidity limitations. In cryptocurrency, backtesting is vital due to the high frequency of market cycles and the volatility of the asset class.
However, it is not a guarantee of future results, as market structures can change rapidly. Traders must ensure that their backtesting environment is as realistic as possible to avoid false confidence.
It is a standard procedure for validating any quantitative trading system.
