Which ITR form should be used for FY 2018 - 2019

I want to know which ITR form I should use for FY 2018 - 2019.

For FY 2016 - 2017 I had used ITR 3 audited as I had speculative losses (intraday and stcl)

For FY 2017 – 2018 I had used ITR3 unaudited as I had non speculative profit (f&o)

For FY 2018 – 2019 I have minor (Rs 400) non speculative losses (f&o), minor stcg (Rs 1000) and carry forward of previous year losses (includes speculative and stcl).

Can I use ITR2 or ITR1 for FY 2018 - 2019 or I need to file ITR3 audited?

What things I should be aware of for FY 2018 – 2019 or next years if I use ITR2 or ITR1 for FY 2018 – 2019?
