Different results in production vs evaluation - Keras Deep Learning

I have built a cryptocurrency regression model but it performs different in real-life then the evaluation over the same period.

I am using exchange binance. In production I call my custom the predict() function each 15min just after the new data sample has closed. Since data is real-time I use the sample at index -2 because -1 is real-time and will still change. I also specify the timestamp of the sample I want in the predict() function so there are …
