Custom GAP UP scanner for NIFTY Stocks

The security function can be called 40 times in a code. We can therefore scan about 40 stocks out of NIFTY 50 stocks with a single script.
This code can be modified to search for other scripts by changing the condition function
condition() => open > (close * 1.0025)

Only stocks which have gap up of 0.25% or more will be reported.
