Hey Omkar,
For point 1, the mt4 limit can be easily increased by changing the chart options. Your broker data will only download so much but you can import data to mt4 much greater than 32k bars.
additionally yes the limit in FSB pro of 200k bars can be easily increased by modifying one of the settings text files, if you can’t find how to do this on google let me know and I’ll help you out.
