EA and indicator adjustments

Dear Sirs, I need the following: - add one option to an existing EA: The EA shell not trade again for the same day if there was a stopped out - Adjust some existing indicators: - Hull Moving Average: There shell no more be an Moving Average printed into the chart, but an histogramm which changes color regarding if Hull MA is pointing upwards or downwards. The oscillator bar shell alwys have the same length - Hull Moving Average II: There shell no more be an Moving Average printed into the chart, but blue arrows shell be printed into the chart for an upward Hull MA, red errors for an downward Hull MA -Standard MACD: no signal line, just histogramm bars in the same lenght, if above zero blue color, if below zero red color - Reverse Engineering of an existing EA Regards
