Custom PSAR EA

I would like a Parabolic Sar EA built that opens buy and sell trades with a sound alert when a signal is triggered (The PSAR changes direction). I would like to close my trades manually. Needs to work on any chart. I would like to be able to select the following parameters: - Lot size. - Step and Maximum value - 4 or 5 digit broker. (4 not necessary but preferred) - max open trades - option to open trades on close of 1st or second bar when direction changes. Kind Regards, Justin Storey
