Predicting future of LSTM resulting in weird answers

Question

so I was recently trying to predict stock prices using an LSTM (seems really overdone I know) but when I was predicting on data that is outside the dataset, I get a really weird graph that I do not think is correct, am I doing something wrong? Prediction: https://github.com/Alpheron/StockPred/blob/master/predictions/MSFT-5-Year-LSTM.ipynb Training: https://github.com/Alpheron/StockPred/blob/master/MSFT-5-Year-LSTM.ipynb In order to process the data, I used the lookback index of 60 points, so when trying to predict on data that is outside of the dataset, I would need the last 60 points as well, but I am I doing something wrong with the way I am predicting?
