I have done ETF ki dukan which u have been successfully running from the last 2 years almost. Now in that case you are buying multiple ETFs when it's in your buy range. But what if you are investing in any ETF for the long term then you can track it using the Google Sheet I have created.
The problem with the broker account is that it can give you holding details and when you have bought it. That's it, you will not get any other information from the broker account. But when you track using the Google Sheet, you cab track everything. When you have bought it, what's the reason for it, when you have sold it, the profit booked and more information.
Say for example, you are investing in NiftyBees, GoldBees and SmallCap ETFs. And what's the best way to track it, nothing. But using teh sheet you can track it every detail. And along with that, if you see the current price is less than your average price, you can continue to buy so that in future it will be helpful to get profit from it.
And it's not that it will work only for the Indian Market, it will work for the stock market of the world. Just that we have to provide proper tag like NSE for Indian and for US proper Google Sheet tag.
