No it is not the job of the broker. The broker is there to advise you and to facilitate you. The profits are yours and the risk is yours too. So the sooner you learn to start taking responsibility and accountability for your trades the better it is. When an investor started trading in the market he was very clear about the maximum loss that he was willing to take upon himself. Each trade of his and his overall approach to markets was driven by managing risk of trades. While he had a bad start, his discipline helped him to tide through the tough times and come out a winner at the end of 1 year. What is important is that the investor never tried to pass the buck for the outcomes to the market or to extraneous factors. Remember, every trader and investor faces extraneous risks. It is the trader who acknowledges and manages it best who comes out a winner!
