I need an EA for MT4 based on MACD cross and Moving Averages.

I need an EA for MT4 based on MACD cross and Moving Averages. Below is a detailed description of the proposed EA. There's also a BUY example attached for clarity.  This EA should work for for all time frames and symbols.

Global Variables

MacDFast    = Fast=12 //Fast EMA Period

MacDSlow    = Slow=26 //Slow EMA Period

MacDSource  = Close   // Applied Price

MacDSignal  = 9       //Signal Line Period

MacDRangeLong  = -4.5,-45.0 //MacD Range for BUY signal when macd cross signal line

MacDRangeShort =  4.5, 45.0 //Range for SELL signal when macd cross signal line

EMA1    = 100 //100 Exponential Moving Average

EMA2    = 125 //125 Exponential Moving Average

EMA3    = 200 //200 Exponential Moving Average

LotSize = 0.01 //Default lot size

AlertOnly  = 0 //When all conditions are met, trigger mt4 alert

TradeOnly  = 0 //When all conditions are met, trigger mt4 trade

TakeProfit = 0 //Take Profit variable is set when conditions are met

StopLoss   = 0 //Stop Loss variable is set when conditions are met

RiskReward = 1.5 //Default risk/reward ratio multiplier

Session    = 0 //0=All Sessions, 1=New York, 2=London, 3=Tokyo, 4=Sydney (User can select multiple sessions)

MutipleOrders = 0 //0=Open Order when conditions are met 1=Only open one order at a time, additional order cannot be opened

ATR = 14 //Average true range used in stop loss calculation

Long: At Candle open

    if (previous candle high and low > EMA1) && (previous candle high and low > EMA2) && (previous candle high and low > EMA3) 

      if (current candle open > EMA1) && (current candle open > EMA2) && (current candle open > EMA3) 

if (macd and signal line cross between MacDRangeLong)

        if(AlertOnly = 1 && TradeOnly  = 0)

(

  StopLoss  = Distance from price to ema2

  TakeProfit = (Distance from price to ema2) * RiskReward

  Alert("Buy at " + CurrentPrice + "Stop Loss " StopLoss + "Take Profit" + TakeProfit )

        )

if(AlertOnly = 0 && TradeOnly  = 1)

        (

  Buy Market Order

  LotSize = LotSize

  StopLoss  = Distance from price to ema2

  TakeProfit = (Distance from price to ema2) * RiskReward

  when ( price = 50% of TakeProfit )

       StopLoss  = break even + 5 pips

  when ( price = TakeProfit )

     Trailing Stop Loss = calculated by subtracting the current ATR value from the lowest-low of the given lookback period 

       )

Short: At Candle open

    if (previous candle high and low < EMA1) && (previous candle high and low < EMA2) && (previous candle high and low < EMA3) 

      if (current candle open < EMA1) && (current candle open < EMA2) && (current candle open < EMA3) 

if (macd and signal line cross between MacDRangeShort)

        if(AlertOnly = 1 && TradeOnly  = 0)

(

  StopLoss  = Distance from price to ema2

  TakeProfit = (Distance from price to ema2) * RiskReward

  Alert("Sell at " + CurrentPrice + "Stop Loss " StopLoss + "Take Profit" + TakeProfit )

        )

if(AlertOnly = 0 && TradeOnly  = 1)

        (

  Sell Market Order

  LotSize = LotSize

  StopLoss  = Distance from price to ema2

  TakeProfit = (Distance from price to ema2) * RiskReward

  when ( price = 50% of TakeProfit )

       StopLoss  = break even + 5 pips

  when ( price = TakeProfit )

     Trailing Stop Loss = calculated by adding the current ATR value to the highest-high of the given lookback period
