One thing about trend line charting is it is based on probability and using historical price actions to plot the future direction. Thus, there will always be a margin of error.
In this case, the price action does not come down to 13,371.50 but rather, rebound at 13,495. So if one remains too rigid and trade on fixed rules rather than market irregularities, then he will missed many a good buy.
If you are not in yet, do not chase the price as it has already went up for 4 consecutive days. Wait for a pullback and based on price action, determine your buy entry at a lower price.
