That reminds me of myself a few weeks after i started out. When I began I had no clue what shorting was. I used to trade JP associates those days.
Once I went long in margin. Around 2PM stock painted one big candle and i was down 30-35k. next candle another 30k and the next another 30k. EOD i was down 1 in lakh. After that i never went long in anything for a year
.
Shorting, I made good money but I burnt my fingers also at times. After 2 years of ups and downs, I had to forcefully and painfully learn to go long.
