crypto price prediction model

In this project we try to make a better model with a focus on validation That is my first model befor make it better with validation

And that is my second model after validation

The core of my model is sth like that

#Initialize the RNN
model = Sequential()
model.add(LSTM(20,return_sequences=True,input_shape=(X_train.shape[1], 4)))
model.add(LSTM(20,return_sequences=True))
model.add(LSTM(20))
model.add(Dense(1))

For more details look at the sorce codes ...
