hello there
I am already using algorithms trading where code is already developed for the same.
my code can download historical data from Yahoo finance directly using scrapping or api both using excel or python both.
now this data is used for calculating SMA, EMA, RSI, MACD, covariance, Regression, BOLLINGER bands etc.
same is used for backtesting and visualization of various trading strategies like crossover SMA or EMA, RSI, MACD strategies.
graphs shown are also dynamic.
Also I can develop portfolio where it shows how much you have invested and got in return.
I can do much more, for more please contact me.
waiting for your response
regards.
