Hi @Goldshine @Richa, As we have explained in our post about charts, the exchange processes millions of transactions each day but as an industry standard, only a snapshot of such transactions/ticks is used for intra-day charts. And hence you may see a variance in intra-day charts among brokers.
The logic for intra-day charts at NSE is also the same - it shows snapshots of transactions and not each transaction.
This just impacts the chart formation and not the actual order execution. The order execution happens at exchanges based on price-time priority and as mentioned in our post, it is possible that the order gets executed at a price that is not seen on charts. Again, this is the same across the industry.
For your reference, here is the Banknifty chart from NSE for today. The high mentioned is 44,339.05, but as you can see the chart shows a high of 44,318, which is the same as open. Even the pre-open high on the chart is 44,436, and not 44,339.05.
Hope this clarifies.
