I am not sure it may help
It wont because none of the brokers we have support mt4 or mt5 platform.
this is because only trading in bse nse and indian stock exchanges is legal in india. Also only 4 forex pairs can be legally traded in india.
So as metatrader is helpful for 24hr trading or better to say forex trading so it is useless for indian brokers to adopt metatrader.
ALl we have is just platforms like zerodha which is sufficient for indian market even though it has high fees and so less options when compared
to even worst of brokers on metatrader.
Do ask for explanation of legality of trading in india though all i can do is just share few links.
