Hi Does zerodha provide a mapping sheet between NSE and BSE symbols. I used to see that eventhough the token is different for a instrument in both exchanges, the trading symbol used to be the same. so this could be used to map both instruments. But today i experienced this, I saw 3 qty holding for NSE: AEGISCHEM, which i never bought. later i found that the stock I bought in BSE: AEGISLOG got converted after T+2 days in to NSE:AEGISCHEM. I have no way of knowing the NSE counterpart.
