As you can see in the chart, a long term trend line is offering support to the today's low, which is not very far from closing.
This line is important for reversal or a short covering bounce up, tomorrow we have a weekly options expiry too. The developments can be interesting.
Traders may use this line to create, hold and book positions tomorrow or for next few days.
12100 is indeed a major support for tomorrow. Trade in either direction keeping this in mind.
