Can minimal speculative income (<500) be filed under ITR2

I tried to explore Intraday trading last year and made a small profit of less than Rs 500. I regularly file my ITR using ITR 2. Can I use ITR2 this year also, and in which case, where can i include my speculative income from intraday trading. If not, is ITR3 mandatory ? I would then need to redo all work and have never filed ITR3 earlier :(.
