An expert advisor based only on candle pattern

Hello! I want to create a trading robot fox xauusd; mql5; based on the 30m timeframe. For a BUY position I want: the "3" candle to be bullish; "2" candle to be bearish; "1" candle to be bullish with the close above the open of "2" candle. Candle "1" needs to have a top wick bigger than 3 pips (30 points). When this happens open a BUY position at the open of the next candle (candle "0" as i show in the image) with the STOPLOSS 2 pips below the low of candle "1" and TP at a 1:1 risk-reward ratio. The stoploss needs to be maximum 25 pips, otherwise do not open the trade. When the "0" candle breaks the high of "1" candle. move the SL 2 pips below the "0" candle. If the trade opens and the 30m candle does not reach TP or SL and it closes bearish, close the trade. If the "0" candle closes bullish but does not reach TP or SL yet, move the SL below the low of "0" candle that just formed. Basically a trailing SL once every candle closes. Also, if the "0" candle closes bullish but with a top wick smaller than 2 pips close the trade in profit. Fix 1 lot/trade. 

Do the same thing for SELL as well.
