Sometimes sentiments may lag due to source e.g Newsarticle published an hour after event, so we will also utilize [tradefollowers](https://www.tradefollowers.com/strength/twitter_strongest.jsp?tf=1d) for their twitter sentiment data. We will process both lists independently and combine them. For both the sentdex and tradefollowers data we use a 30 day time period. Using a single day might be great for day trading but increases probability of jumping on false rallies.

# Indicators give us an idea of the direction of future prices. For instance, the Exponential moving average (EMA) crossing the Simple moving average (SMA) might indicate a positive uptrend in price. RSI gives us an idea of how much the stock is being bought or sold. An RSI of 70 for instance might indicate an overbought stock, and tells us the price is very likely to go down in the future, while an RSI of 30 indicates an oversold stock and could potentially be a good buy point for a stock. On balance volume gives us the relative changes in volume, and can potentially identify true rallies or breakouts. Bollinger bands provide an idea of the volatility of the stock.

# The closing price has very strong correlations with some of the other price informations such as opening price, highs and lows.
# On the other hands, the differential prices arn't as correlated. We want to limit the amount of colinearity in our system before running any machine learning routine. So feature selection is a must.
# ### Feature Selection
#
# We utilize two means of feature selection in this section. Random forests and mutual information gain. Random forests are
# very popular due to their relatively good accuracy, robustness as well as simplicity in terms of utilization. They can directly measure the impact of each feature on accuracy of the model and in essence give them a rank. Information gain on the other hand, calculates the reduction in entropy from transforming a dataset in some way. Mutual information gain essentially evaluates the gain of each variable in the context of the target variable.
# In[85]:
# ### Random forest regressor
# In[88]:
# Seperate the target variable from the features
y = df_updated['Close'].iloc[1:].dropna()
X = df_updated.drop(['Close'], axis=1).iloc[1:].dropna()
#print("y-Band: ",y.count)
#print("x-band: ",X.count)

X_train, X_test, y_train, y_test = train_test_split(X,
y,
test_size=0.2,
random_state=0)
# In[90]:
X_train.shape, y_train.shape
# In[92]:
feat = SelectFromModel(
RandomForestRegressor(n_estimators=100, random_state=0, n_jobs=-1))
feat.fit(X_train, y_train)
feat.get_support()
# In[93]:
X_train.columns[feat.get_support()]
# The regressor essentially selected the features that displayed good correlation with the Close price. However, although it selected the most important we would like information on the information gain from each variable. An issue with using random forests is it tends to diminsh the importance of other correlated variables and may lead to incorrect interpretation. However, it does help reduce overfitting
# ### Mutual information gain
# In[94]:
# In[96]:
mi = mutual_info_regression(X_train, y_train)
mi = pd.Series(mi)
mi.index = X_train.columns
mi.sort_values(ascending=False, inplace=True)
# In[97]:
st.table(mi.head(50))
# The results validate the results using the random forest regressor, but it appears some of the other variables also contribute
# a decent amount of information. We will select values greater than 2 for our analysis.
# In[98]:
sel = SelectKBest(mutual_info_regression, k=8).fit(X_train, y_train) #
Features = X_train.columns[sel.get_support()]

# ### Preprocessing
#
# In order to construct a Long short term memory neural network (LSTM), we need to understand its structure. Below is the design of a typical LSTM unit. Data source: [Researchgate](https://www.researchgate.net/publication/334268507_Application_of_Long_Short-Term_Memory_LSTM_Neural_Network_for_Flood_Forecasting)
# 
# As mentioned earlier, LSTM's are a special type of Recurrent neural networks (RNN). Recurrent neural networks (RNN) are a special type of neural network in which the output of a layer is fed back to the input layer multiple times in order to learn from the past data. Basically, the neural network is trying to learn data that follows a sequence. However, since the RNNs utilize past data, they can become computationally expensive due to storing large amouts of data in memory. The LSTM mitigates this issue, using gates. It has a cell state, and 3 gates; forget, imput and output gates.
#
# The cell state is essentially the memory of the network. It carries information throughtout the data sequence processing. Information is added or removed from this cell state using gates. Information from the previous hidden state and current input are combined and passed through a sigmoid function at the forget gate. The sigmoid function determines which data to keep or forget. The transformed values are then multipled by the current cell state.
#
# Next, the information from the previous hidden state combined with the input is passed through a sigmoid function to again determine important information, and also a tanh function to transform data between -1 and 1. This transformation helps with the stability of the network and helps deal with the vanishing/exploding gradient problem. These 2 outputs are multiplied together, and the output is added to the current cell state with the sigmoid function applied to it to give us our new cell state for the next time step.
#
# Finally, the information from the hidden state combined with the current input are combined and a sigmoid function applied to it. The new cell state is passed through a tanh function to transform the values and both outputs are multiplied to determine the new hidden state for the next time step.
#
# Now we have an idea of how the LSTM works, let's construct one. First we split our data into training and test set
# In[99]:
df_updated.reset_index(drop=True, inplace=True)
train_size = int(len(df_updated) * 0.8)
test_size = len(df_updated) - train_size
# Make sure to omit the first row, contains NAN's
train = df_updated.iloc[1:train_size]
test = df_updated.iloc[train_size:]
# In[100]:
train.shape, test.shape
# In[102]:
# Extract the features
total_features = list(Features.values)
total_features.append('Close')
total_features
train = train[total_features]
test = test[total_features]
train.shape, test.shape
# Before we proceed, it is important to scale the data. Scaling is done to ensure one set of features don't have more importance relative to the others. In addition, having values between 0 and 1 will help the neural network converge faster if at all it does. We apply different scalings to the test and training data to avoid leakage into our model.
# In[103]:
# Scale both features and target variables
f_transformer = MinMaxScaler() # Feature scaler
targ_transformer = MinMaxScaler() # Target scaler
f_transformer = f_transformer.fit(train[Features].to_numpy())
targ_transformer = targ_transformer.fit(train[['Close']])
train.loc[:,
Features] = f_transformer.transform(train[Features].to_numpy())
train['Close'] = targ_transformer.transform(train[['Close']].to_numpy())
test.loc[:, Features] = f_transformer.transform(test[Features].to_numpy())
test['Close'] = targ_transformer.transform(test[['Close']].to_numpy())

# The figure below shows how the sequential data for an LSTM is constructed to be fed into the network. Data source: [Althelaya et al, 2018](https://ieeexplore.ieee.org/document/8355458)
# 
# Bassically for data at time t, with a window size of N, the target feature will be the data point at time t, and the feature will be the data points [t-1, t-N]. We then sequentially move forward in time using this approach. We therefore need to format our data that way.

# ### Building LSTM model
#
# The new installment of tensorflow (Tensorflow 2.0) via keras has made implmentation of deep learning models much easier than in previous installments. We will apply a bidrectional LSTM as they have been shown to more effective in certain applications (see [Althelaya et al, 2018](https://ieeexplore.ieee.org/document/8355458)). This due to the fact that the network learns using both past and future data in 2 layers. Each layer performs the operations using reversed time steps to each other. The loss function in this case will be the mean squared error, and the adam optimizer with the default learning rate is applied.
# In[110]:
# In[111]:
model = keras.Sequential()
model.add(
keras.layers.Bidirectional(
keras.layers.LSTM(units=32,
input_shape=(X_train_lstm.shape[1],
X_train_lstm.shape[2]))))
model.add(keras.layers.Dropout(rate=0.2))
model.add(keras.layers.Dense(units=1))
# In[112]:
model.compile(optimizer='adam', loss='mean_squared_error')
# In[114]:
history = model.fit(X_train_lstm,

test_loss = model.evaluate(X_test_lstm, y_test_lstm)
# In[116]:
# In[117]:
plot_learningCurve(history, 90)
# With each epoch, the validation loss is decreasing but in a bit of a stochastic manner. The training loss is fairly consisten throughout. There maybe some overfitting in there but you can always tune model parameters and explore data more. Let's make some predictions on the test data just to see what's happening
# In[118]:
y_pred = model.predict(X_test_lstm)
# We need to apply some inverse scaling to get back our original results.
# In[119]:
y_train_inv = targ_transformer.inverse_transform(
y_train_lstm.reshape(1, -1))
y_test_inv = targ_transformer.inverse_transform(y_test_lstm.reshape(1, -1))
y_pred_inv = targ_transformer.inverse_transform(y_pred)
# In[120]:

# At first glance we can see that the our predictions are not very great, we could define adjust our model parameters some more. However, they appear to be following the trends pretty well. Let's take a closer look
# In[121]:
plt.figure(figsize=(10, 10))
plt.plot(np.arange(len(y_train_lstm[0:500], ),
len(y_train_lstm[0:500]) + len(y_test_lstm[0:500])),
y_test_inv.flatten()[0:500],
label="true")
plt.plot(np.arange(len(y_train_lstm[0:500]),

plt.xlabel('Time Step')
plt.legend()
st.pyplot(plt, use_container_width=True)
#plt.show();
# Now it will become apparent why I did not use a large amount of epochs to train my model. At first glance, we notice the LSTM has some implicit autocorrelation in its results since its predictions for a given day are very similar to those of the previous day. It essentially lags. Its basically showing that the best guess of the model is very similar to previous results. This should not be a surprising result; The stock market is influenced by a number of factors such as news, earnings reports, meargers etc. Therefore, it is a bit too choatic and stoachastic to be acurately modelled because it depends on so many factors, some of which can be sporadic i.e positive or negative news. Therefore in my opinion, this may not be the best way to predict stock prices. Of course with major advances in AI there might actually be a way, but I don't think the hedge funds will be sharing their methods anytime soon.
# ## Part 3: Regression analysis
# Of course we could still make an attempt to have an idea of what the possible price movements might be. In this case I will utilize the differential prices as there's less volatility compared to using absolute prices. Let's explore these relationships

# Above are a series of plots that show the relationship between different differential price measurements and the differential close. In this study, the differece relates to the difference between a value at time t and the previous day value at time t-1. The Differential high, differential low, differential high-low and differential open-close appear to have a linear relationship with the differential close. However, only the differential open-close would be useful in an analysis. This because on a given day (time t), we can not know what the highs or lows are before hand till the day ends. However, we know the open value at the start of the trading period.

# We obtained a mean square error of 0.58 which is fairly moderate. Our R^2 value basically says 54% of the variance in the
# differential close price is explained by the differential open-close price. Not so bad so far. But to be truly effective, we need to make use of statistics. Specifically, let's define a confidence interval around our predictions i.e prediction intervals.
#
# Prediction intervals give you a range for the prediction that accounts for any threshold of modeling error. Prediction intervals are most commonly used when making predictions or forecasts with a regression model, where a quantity is being predicted. We select the 95% confidence interval in this example such that our actual predictions fall into this range 99% of the time.
