Using stock historical data, train a supervised learning algorithm with any combination of financial indicators. Rapidly backtest your model for accuracy and simulate investment portfolio performance.
pip install clairvoyantpython -m pip install git+https://github.com/anfederico/clairvoyantDuring the testing period, the model signals to buy or sell based on its prediction for price movement the following day. By putting your trading algorithm aside and testing for signal accuracy alone, you can rapidly build and test more reliable models.
from clairvoyant.engine import Backtest

Once you've established your model can accurately predict price movement a day in advance, simulate a portfolio and test your performance with a particular stock. User defined trading logic lets you control the flow of your capital based on the model's confidence in its prediction and the following next day outcome.
def logic(account, today, prediction, confidence):
if prediction == 1:
Risk = 0.30
EntryPrice = today['close']
EntryCapital = account.BuyingPower*Risk
if EntryCapital >= 0:
account.EnterPosition('Long', EntryCapital, EntryPrice)
if prediction == -1:
ExitPrice = today['close']
for Position in account.Positions:
if Position.Type == 'Long':
account.ClosePosition(Position, 1.0, ExitPrice)
simulation = backtester.Simulation(features, trainStart, trainEnd, testStart, testEnd, buyThreshold, sellThreshold, continuedTraining)
simulation.start(data, 1000, logic, kernel='rbf', C=1, gamma=10)

The primary purpose of this project is to rapidly test datasets on machine learning algorithms (specifically Support Vector Machines). While the Simulation class allows for basic strategy testing, there are other projects more suited for that task. Once you've tested patterns within your data and simulated a basic strategy, I'd recommend taking your model to the next level with:

The examples shown use data derived from a project where we are data mining social media and performing stock sentiment analysis. To get an idea of how we do that, please take a look at:
