Ashok Leyland has the best chart I have seen today. Here are some of the pointers from the chart:
Look at the trend-line. This is a very important trendline.
S1 and S2 provided good support to the stock previously.
4th January 2019 was when the trend-line was decisively broken and there was a down fall.
R1 and R2 offered great resistances. This is in line with the theoretical definition of a support trend-line, ie, "A previous support trend-line then acts like a resistance".
Previous session saw fantastic volumes on the chart and a confirmation upward move in today's session could be an entry point for the chart.
