#CurrencyPairPrediction Common Pitfalls to Avoid Pitfall Explanation Lookahead bias Accidentally using future data to make decisions. Survivorship bias Only using data from assets that survived (ignoring those that disappeared). Overfitting Making the model too perfect on historical data but useless in the future. Ignoring trading costs Assuming trades are free leads to unrealistic performance. Data snooping Trying too many models/strategies on the same data set can make results misleading.
