Currently I am calling API for instruments to fetch all the instruments. https://api.kite.trade/instruments/MCX - Though there is column of lot_size it's showing wrong information.
E.g., For Gold should be trade at 1KG so as we are showing price in 10KG we should have a way to identify that when user trade one we have to multiply it by 100 and for GOLD MINI 10.
Currently, in instruments.csv we don't have a lot size detail for MCX contracts. It don't change so often, so maybe you can set this multiplier constant at your end. You can refer to this post.
@dhavalsoni2001 Its not possible to include multiplier in the instruments as of now. However, we have added the multiplier for all MCX contracts in this public google sheet(Column 9). You can automate pulling multipliers for this sheet for your P&L calculation. Our RMS team updates this regularly.
