FOREX need HELP with my auto sys buy and sell Signals? -

Iv mostly got it set up the way i like, just one minor problem i don t know how to change. When the line goes Over the candle stick its a sell signal and when it goes under the candle stick it is supposed to make a buy signal and it does BUT the problem is that the system keeps making BUY and SELL Points all the way up or down the trend. So if the trend is going to go down and it says sell i just want the system to sell at the first signal when its at the top not have a ton of buy and sell signals all the way down and up just one buy and one sell. WHAT do i change ? It would be quite helpful if you told us what system you are referring to. Many people on this channel do not rely on signal systems to tell us when to buy or sell a position. Paul
