Need help to create an EA for Pending Orders

Hello MQL5 freelancers, good day.

I’m just starting to learn MQL5 and I’ve started reading the MQL5 Docs and a couple tutorials for beginners but haven’t found a good tutorial on how to place pending orders using Buy Stop and Sell Stop. I would like to know if anybody could teach me how to do what I need with one or two freelance jobs, this way I could get the grasp of it a little bit faster and start learning by the example of an experienced MQL5 programmer.

Here are the basic rules for my first EA:

1. Check ADX Indicator and determine if +DI > -DI or +DI < -DI; assign this to variables used for next steps.

    a) Buy_Condition = +DI > -DI;

    b) Sell_Condition = +DI < -DI;

2. If +DI > -DI the order should be Buy Stop and if +DI < -DI the order should be Sell Stop.

    a) If +DI > -DI look for black candles (bears) and if +DI < -DI look for white candles (bulls).

    b) Once this conditions are met respectively, open a position to buy or sell (depending on the criteria) with Open price from previous bar/candle.

3. If the order is Buy Stop, Stop Loss should be equal to: Low price from previous bar/candle -0.1 cents; if the order is Sell Stop, Stop Loss should be equal to: High price from previous bar/candle +0.1 cents.

4. The timeframe/period for this should be daily (D1).

For this EA I think I won’t be needing Moving Average nor Take Profit.

Here is the code I have started to create but could't place any orders yet:

// Input variables

input double Lots    = 0.1;

input int StopLoss   = 1000;

input int TakeProfit = 1000;

input int MAPeriod   = 10;

input int ADXPeriod  = 14;

// Global variables

bool glBuyPlaced, glSellPlaced;

// OnInit() event handler

int OnInit()

  {

//---

   

//---

   return(0);

  }

// OnTick() event handler

void OnTick()

{

// Trade structures

MqlTradeRequest request;

MqlTradeResult result;

ZeroMemory(request);

// Moving average

double ma[];

ArraySetAsSeries(ma,true);

int maHandle=iMA(_Symbol,0,MAPeriod,MODE_SMA,0,PRICE_CLOSE);

CopyBuffer(maHandle,0,0,1,ma);

// ADX Indicator values

double ADX_Val[], Plus_DI[], Minus_DI[];

ArraySetAsSeries(ADX_Val,true);

ArraySetAsSeries(Plus_DI,true);

ArraySetAsSeries(Minus_DI,true);

int ADX_Handle = iADX(NULL, 0, ADXPeriod);

CopyBuffer(ADX_Handle, 0, 0, 3, ADX_Val);

CopyBuffer(ADX_Handle, 1, 0, 3, Plus_DI);

CopyBuffer(ADX_Handle, 2, 0, 3, Minus_DI);

// Open price

double open[];

ArraySetAsSeries(open,true);

CopyOpen(_Symbol,0,0,1,open);

// High price

double high[];

ArraySetAsSeries(high,true);

CopyHigh(_Symbol,0,0,1,high);

// Low price

double low[];

ArraySetAsSeries(low,true);

CopyLow(_Symbol,0,0,1,low);

// Close price

double close[];

ArraySetAsSeries(close,true);

CopyClose(_Symbol,0,0,1,close);

// Current position information

bool openPosition = PositionSelect(_Symbol);

long positionType = PositionGetInteger(POSITION_TYPE);

double currentVolume = 0;

if ( openPosition == true ) currentVolume = PositionGetDouble(POSITION_VOLUME);

// Open buy market order

if ( Plus_DI[0] > Minus_DI[0] && glBuyPlaced == false && (positionType != POSITION_TYPE_BUY || openPosition == false) )

{

request.action = TRADE_ACTION_PENDING;

request.type = ORDER_TYPE_BUY_STOP;

request.symbol = _Symbol;

request.volume = Lots + currentVolume;

request.type_filling = ORDER_FILLING_FOK;

request.price = SymbolInfoDouble(_Symbol,SYMBOL_ASK);

request.sl = 0;

request.tp = 0;

request.type_time = ORDER_TIME_SPECIFIED;

request.deviation = 50;

request.stoplimit = 0;

OrderSend(request,result);

// Modify SL/TP

if ( result.retcode == TRADE_RETCODE_PLACED || result.retcode == TRADE_RETCODE_DONE )

{

request.action = TRADE_ACTION_SLTP;

do Sleep(100); while(PositionSelect(_Symbol) == false);

double positionOpenPrice = PositionGetDouble(POSITION_PRICE_OPEN);

if ( StopLoss > 0 ) request.sl = positionOpenPrice - (StopLoss * _Point);

if ( TakeProfit > 0 ) request.tp = positionOpenPrice + (TakeProfit * _Point);

if ( request.sl > 0 && request.tp > 0 ) OrderSend(request,result);

glBuyPlaced = true;

glSellPlaced = false;

}

}

// Open sell market order

else if ( Minus_DI[0] < Plus_DI[0] && glSellPlaced == false && positionType != POSITION_TYPE_SELL )

{

request.action = TRADE_ACTION_PENDING;

request.type = ORDER_TYPE_SELL_STOP;

request.symbol = _Symbol;

request.volume = Lots + currentVolume;

request.type_filling = ORDER_FILLING_FOK;

request.price = SymbolInfoDouble(_Symbol,SYMBOL_BID);

request.sl = 0;

request.tp = 0;

request.type_time = ORDER_TIME_SPECIFIED;

request.deviation = 50;

request.stoplimit = 0;

OrderSend(request,result);

// Modify SL/TP

if ( (result.retcode == TRADE_RETCODE_PLACED || result.retcode == TRADE_RETCODE_DONE) && (StopLoss > 0 || TakeProfit > 0) )

{

request.action = TRADE_ACTION_SLTP;

do Sleep(100); while(PositionSelect(_Symbol) == false);

double positionOpenPrice = PositionGetDouble(POSITION_PRICE_OPEN);

if ( StopLoss > 0 ) request.sl = positionOpenPrice + (StopLoss * _Point);

if ( TakeProfit > 0 ) request.tp = positionOpenPrice - (TakeProfit * _Point);

if ( request.sl > 0 && request.tp > 0 ) OrderSend(request,result);

glBuyPlaced = false;

glSellPlaced = true;

}

}

} 

I hope someone could point me in the right direction and help me to solve this EA.

Regards and thank you in advance,
