“Very apt for trading too” - Credits to my friend on a trading slack group 
I started off with paper trading in forex markets (i had this metatrader app with 500x leverage and virtual money) in 2012 
- FEMA regulations, was actually scared to put in real money, then paper trading low priced/ penny stocks (<20) in bse market (ashley, birla costyn, unitech) - all excel sheet/program outputs were good, low volumes, hence no trades. Then NSE blue chips (i dunno why). Then only SBI. Then nifty futures (listened to tipsters on whatsapp - worst decision i have ever made - lost a lot of money). Gave my account to a PMS guy, one Mr. Tushar (he burnt 80% of the account in a few months). Then stock futures (only HDFC bank 20% bank). and finally ended now in index option writing. The journey still continues…
I started a blog niftybanknifty.com to assist fellow index option writers. Join the telegram group & whatsapp group here. No tips/BS in the groups!
