Initial SMA (Simple Moving Average) implementation.
It gets a CSV file exporded from DB (one-day snapshot), imports it into a Pandas DataFrame, then implements SMA low/high, indicators A,B,C, bullish/bearish market as well as signals to buy/sell.
TA-Lib installation is required.
TODO: better detection of intersection of the indicators... some false positive signals because plots are too close to each other and difference is smaller then epsilon.
