Work and trading is a bad idea. If the investment on with a small period it is possible. You will be constantly distracted and you have bad will happen at work. Better select amount and enter the wait of a week or more.
When you do have a hectic schedule and you did decide to make tradings in the middle then you will surely put the risk of your day work which isnt really good. Focus would be lost and might cause for you to fail or do such mistakes on your job which would possible cause to make problems later on. If you can able to handle your time well then it isnt bad to engage on both things as long you do know how to allocate well your time.
