Support Resistance Exercise : Why I don't follow it

Hello There,

I do not know if you ever tried this this or not, but I would like you to do a small exercise and share your observation on comment section -

What to do -
1. Open BNK or NIFTY chart (cash Future etc) and Go to back dated chart like 5 or 8 months back
2. Now draw a random Horizontal line at any price level
3. Now slowly move the chart on forward direction and Check how perfectly your horizontal line worked as support and resistance to trade
4. Use this on the time frame in which you prefer to work


Regards,
