Metatrader Indicator improvement T-Sig

Thank you for looking at my project. I have a MTF indicator attached that sometimes does not always update. If I change the timeframe and come back to the original timeframe, I have an arrow that was not there before I went to the other TF. The indicator is an RSI crossing 50 with 2 EMA’S for a filter. The indicator gives me the option to plot the EMA’S which I don’t need if it simplifies things, the ema's can be removed. I also would like to add the currency pair of the chart into the alert as well as timeframe so I know where to look for the alert. If you are not familiar with Metatrader or the details of indicator updating, please don’t bid.
