Intraday Trading is a Myth for 99.99% of us

Guys, sharing my experience of intra-day trading. I had made about 35L in 2015 trading only Commodities for 3 months, started with capital of 80K and increased to 4L with profits and then kept withdrawing every day my profits. But that was it, afterwards i kept loosing and in next 7 months lost 42 Lakh INR. This was my best in last 8 years of trading experience. hence INtra-day trading is not profitable on long run. Please ponder your view if you do not agree with it. ( Also i am sure many of us like me made 200% to 500% profit in single day , but that in long run was not even 10% )
