90% accuracy...No one has that accuracy.
Just assume if someone has that accuracy then that person will be richest person on earth within 1 year.
Don't look for tips. I have seen one boarder valine on moneycontrol and he has got 35000 followers and most of his calls are so wrong.
In my signature, you can see "Teach a man by Saint" pdf, go through it, learn, paper trade and then invest.
P.S. Even with 40% accuracy, you can make money if you follow risk management.
