Today's sudden crash is causing me a huge loss on my investment but I am not going to sell them like everyone. At such situation small traders panic and sell, thinking they are saving their money but actually they are losing it. Selling at such situation unrealized PNL becomes realized PNL.
My Advice:
Just don't panic and wait for prices to go high again and then sell.
Everything that it requires to be a successful trader is "PATIENCE".
