Simple Buy Sell EA

Hi guys  I'm looking for an EA that;
>Opens long trade if the previous candle is bullish
>Opens short trade if the previous candle is bearish.
>Has the option of SL and TP
>Has the option of adjusting lot size
>Has the option of setting a magic number.
>Can work on any timeframe
If two (or more) subsequent candles are in a similar direction, the EA needn't open a new trade but maintain the existing one. In a nutshell, the EA should only open a new trade if the candle direction changes regardless of any TP/SL already set. Therefore, there should always be a running trade.
Can anyone code this for me...pleeeaasee :-) :-)
