We certainly ran into some problems such as the market behaviour i.e markets are closed on weekends and our project was trying to predict the numerical values even on sundays and hence we overcome this piece of cake by looping into the month and eradicating the weekends to provide the best accuracy and prediction of stocks.
Another problem we ran into that it was'nt calcualating the entry and exit date of the particular stocks or options according to our requirements and hence we also overcomed by applying permutaions and combinations in our looping which makes available to us the entry and exit points we require.
