Do you think you can replace the parabolic with this custom indicator. The indicator basically plot arrows on the chart, red for down and blue for up. The indicator has several indicators working together to give the signal, parabolic included, anyway there is a manual trading system based on this and I think EA as well.
You could leave the current parabolic as is and use the two indy to confirm each other for signal. Maybe have a extern disable option for both indicator anyway what ever suits you best. Thanks again
