Could you share screenshots of your error and check the logs (orders sent)? 

Usually, there are three types of problems:

- Or the lot size is below the minimum lot size authorized for the symbol and by your broker.

- Or the lot size is above the maximum lot size authorized for the symbol and by your broker.

- Or the lot size’s digits are too numerous. For instance, some brokers will allow 10.003 volume, while others don’t allow more than 2 digits of precision. This is called the lot step. If that is your problem, try round to the second digit.

Yes, it seems I was using digits for rounding while I should have used min vol as I have a function which return the number of digits after 0. So @ William someone have a crystal ball after all.
