@Tejas Khoday ,
I run these on two different systems , so that cannot be the reason for the lag. sometime back i used to run two nest systems from different brokers on the same system and didn't have an issue.
i do understand your involvement and interest in addressing issues raised by the members in this forum. But when you start justifying a certain issue , then it leaves a bad taste. it will sort of give the impression that you want to skirt it.
That aside i have another observation, In the nest trader when i invoke the market depth window/ snap quote window, it launches in a small pop-up. now i can use this to check on various options pricings/ other quote pricing instantly for reference, i find this very useful since it gives a very easy access to various quotes without having to actually add the scrips to the watchlist. this is not possible with fyersone. supposing i want to check the option pricing of different strike prices/type etc., of a scrip or index, i have to add each one of them to the watchlist. this is quite cumbersome.
maybe you could look at easing this function.
