Data interpretation varied from person to person. For some person, a partial data may be meaningless but for someone, it may be useful... Every time comparing your strategies with other (only EQ) is not good.
I don't track DF data, I track only equity cash & f&o data. I found it very useful, to judge the market sentiment for so many years...
Yesterday, it showed me negative/cautious sentiment from some large investors(I said..delivery based profit booking happened only after analyzing Equity data), it reflected on today's movement very well.
Yesterday's analysis helped me to gain good profit @ opening hour trading again.
These sentiments usually good for short term, mostly reflect on next day/few days. Investors mood can change quickly according to various news flow/geopolitical/events. But such EQ eod data analyzing helps me to judge the short term sentiment.
The same chunk of data may be meaningless, for someone, but it's may be useful for another one. Nothing personal...But, don't interfere others analyzing method.
