Hi ahmadaboud,
The added characters after the symbol is just the brokers way of identifying the name of the chart. The robots do not read the chart name, they read the bars or candles on the chart. If you are using MT4 and see a smiley face in the upper right corner of the chart, or if you are using MT5 and see a blue hat in the upper right corner of the chart, then the robots are working correctly.
