All right, learn from your own mistakes. You describe your problem very clearly. so try to change it,
Use lot fix size, 0.05 to 0.1 will be appropriate for your consideration and do not start too
many investments in the same time period. Set up a business desk / time routine for business
and fix as much time as possible for business each day according to your dealing style.
And I would recommend to use stop loss and take income goals in each role. and looking for a small income and trying to get it instead of following the big income.
