问题描述
我对编写mql4代码很陌生，如果在以下烛形图出现时能得到一些绘制矩形的帮助，将不胜感激.

并以指定的点数止损和止盈开立挂单.
请原谅我不直接包含图片.我没有足够的赞成票.
以下是链接图像中烛台图案的说明:
需求区
一般candlestick pattern(需求区域)发生在至少两个或多个连续的看涨蜡烛(最后一个看涨蜡烛的高点是该时间段的高点)之后，接着是一个或多个看跌蜡烛，其高点和低点分别为低于最后一个看涨的蜡烛.然后最后是形成新高的看涨蜡烛.需求区域的矩形区域是从最后一个看跌蜡烛的开盘价到最低价.
隐藏需求区
当一系列连续的看涨蜡烛的蜡烛低位，低于前一根蜡烛且其高位与收盘价重合时，则隐藏需求区域将从看涨蜡烛的低位转向开盘.
>完整的解释可在此处获得./p> 我知道bullish和bearish蜡烛可以由
if ( ( Open[1] - Close[1] ) > 0)
{
// candle is bearish
}
else
{
// candle is bullish
}
我非常感谢您的帮助.
似乎这些模式没有完整描述，因此无法正确编码.好的，让我们尝试模式1.用于图案的条件(从图片看似合理):
1.检查新栏的开始(bar#0).
2.小节1(如果我们将0计算为当前值，则为MQL4中的小节#3)必须看涨.
3.第2条(第2条)看跌. (如果是模式#2，则为N条，N可以为2或更大)4.第3条(MT4中的第1条)看涨.
5.其最高价=收盘价.
6.其最高价>最高价#3.

您在这里还需要什么?要检测矩形的HL?这很简单，规则很明确.让我们假设它们是:对于LONG，向上=条形#2的打开，向下=该条形的低.然后，
void detectRangeOfZone(double &top,double &bottom,const EnmDir dir)
{
if(dir>0)
{
top=iOpen(_Symbol,0,2);
bottom=iLow(_Symbol,0,2);
}
else if(dir<0)
{
top=iClose(_Symbol,0,2);
bottom=iHigh(_Symbol,0,2);
}
}
您需要绘制一个矩形吗?好的，但是您将如何决定何时停止绘制?让我们假设右边的N条就足够了，现在让我们忽略周末(如果要记住在市场关闭时的周末会稍微复杂一些).
bool drawRectangle(const int dir,const double top,const double bottom)
{
const datetime starts=iTime(_Symbol,0,2), ends=starts+PeriodSeconds()*N_bars;//time of start and end of the rectangle
const string name=prefix+"_"+(dir>0?"DEMAND":"SUPPLY")+"_"+TimeToString(starts);//name would be unique sinse we use time of start of the range. DO NOT FORGET about prefix - it should be declared globally, you would be able to delete all the objects with 'ObjectsDeleteAll()' function that accepts prefix in one of its implementations.
if(!ObjectCreate(0,name,OBJ_RECTANGLE,0,0,0,0,0))
{
printf("%i %s: failed to create %s. error=%d",__LINE__,__FILE__,name,_LastError);
return false;
}
ObjectSetInteger(0,name,OBJPROP_TIME1,starts);
ObjectSetInteger(0,name,OBJPROP_TIME2,ends);
ObjectSetDouble(0,name,OBJPROP_PRICE1,top);
ObjectSetDouble(0,name,OBJPROP_PRICE2,bottom);
//add color, width, filling color, access modifiers etc, example is here https://docs.mql4.com/ru/constants/objectconstants/enum_object/obj_rectangle
return true;
}
这是主要块，请不要忘记添加一个新的条形检查，否则该工具将在每个刻度上检查对象，这是浪费时间. 字符串前缀=";//为您的所有对象添加一些唯一的前缀 const int N_bars = 15;//在此示例中为15个小节
void OnDeinit(const int reason){ObjectsDeleteAll(0,prefix);}
void OnTick()
{
if(!isNewBar())
return; //not necessary but waste of time to check every second
const bool pattern1Up=isPattern1Detected(1), pattern1Dn=isPattern1Detected(-1);
if(pattern1Up)
{
double top,bottom;
detectRangeOfZone(top,bottom,1);
drawRectangle(1,top,bottom);
PlacePendingOrder(1,top,bottom);
}
if(pattern1Dn)
{
double top,bottom;
detectRangeOfZone(top,bottom,-1);
drawRectangle(-1,top,bottom);
PlacePendingOrder(-1,top,bottom);
}
}
int PlacePendingOrder(const EnmDir dir,const double oop,const double suggestedSl)

I am quite new to writing mql4 code and would be grateful if I could get some help drawing rectangles when the following candlestick patterns occur:

and opening a pending order with specified pips Stop Loss and Take Profit.
Pardon me for not including the images directly. I don't I have enough upvotes to do that.
Here is an explanation of the candlestick patterns in the linked images:
Demand Zone
The general candlestick pattern (Demand Zone) occurs when at least two or more consecutive bullish candles (with the last bullish candle high being the high of the time period) are followed by one or more bearish candles whose high and low are lower than the last bullish candle. Then finally followed by a bullish candle that forms the new high. The rectangle area which is the Demand Zone is taken from the Open to the Low of the last last bearish candle.
Hidden Demand Zone
When a series of consecutive bullish candles has a candle with its low, lower than the previous candle and its High coinciding with its Close, then the Hidden Demand Zone is taken from the low to the open of the bullish candle.
The full explanation is available here for both demand and supply zones.
I am aware that bullish and bearish candles can be determined by
if ( ( Open[1] - Close[1] ) > 0)
{
// candle is bearish
}
else
{
// candle is bullish
}
I would really appreciate some help.
Seems these patterns are not fully described, so it is not possible to code them correctly. Ok, let us try with pattern#1.The conditions used for pattern(what seems reasonable from the picture):
1. check at start of the new bar(bar#0).
2. bar 1(which is bar#3 in MQL4 if we compute 0 as the current) must be bullish.
3. bar 2(bar#2) is bearish. (or N bars in case of pattern#2, N can be 2 or more)4. bar 3(bar#1 in MT4) is bullish.
5. its high=close.
6. its high>high of bar#3.
enum EnmDir
{
LONG = 1,
SHORT=-1,
NONE = 0,
};
int getCandleDirection(const int shift)
{
const double open=iOpen(_Symbol,0,shift), close=iClose(_Symbol,0,shift);
if(close-open>_Point/2.)
return LONG; //bullish
if(open-close>_Point/2.)
return SHORT; //bearish
return NONE; //doji
}
bool isPattern1Detected(const EnmDir dir)
{
if(dir==0)return(false);
if(getCandleDirection(3)!=dir)
return false; //rule#2
if(getCandleDirection(2)+dir!=0)
return false; //rule#3
if(getCandleDirection(1)!=dir)
return false; //rule#4
if(dir>0)
{
if(iHigh(_Symbol,0,1)-iClose(_Symbol,0,1)>_Point/2.)
return false; //rule#5 for long
if(iHigh(_Symbol,0,1)-iHigh(_Symbol,0,3)>_Point/2.)
return true; //rule#6 for long
return false; //if rule#6 is not hold
}
else
{
if(iClose(_Symbol,0,1)-iLow(_Symbol,0,1)>_Point/2.)
return false; //rule#5 for short
if(iLow(_Symbol,0,3)-iLow(_Symbol,0,1)>_Point/2.)
return true; //rule#6 for short
return false; //if rule#6 is not hold
}
}
bool isPattern2Detected(const EnmDir dir,const int numCandlesAgainst=1)
{
if(dir==NONE)return(false);
if(getCandleDirection(1)!=dir)
return false; //rule#4
for(int i=1;i<=numCandlesAgainst;i++)
{
if(getCandleDirection(1+i)!=dir)
return(false); //rule#3 - checking that all numCandlesAgainst must be bearish
}
if(getCandleDirection(2+numCandlesAgainst)!=dir)
return false; //rule#2
if(dir>0)
{
if(iHigh(_Symbol,0,1)-iClose(_Symbol,0,1)>_Point/2.)
return false; //rule#5 for long
if(iHigh(_Symbol,0,1)-iHigh(_Symbol,0,2+numCandlesAgainst)>_Point/2.)
return true; //rule#6 for long
return false; //if rule#6 is not hold
}
else
{
if(iClose(_Symbol,0,1)-iLow(_Symbol,0,1)>_Point/2.)
return false; //rule#5 for short
if(iLow(_Symbol,0,2+numCandlesAgainst)-iLow(_Symbol,0,1)>_Point/2.)
return true; //rule#6 for short
return false; //if rule#6 is not hold
}
}
What else you need here? To detect HL of the rectangle? That is simple, is rules are clear. Let us assume they are: for LONG, up=Open of bar#2, down=low of that bar. Then,
void detectRangeOfZone(double &top,double &bottom,const EnmDir dir)
{
if(dir>0)
{
top=iOpen(_Symbol,0,2);
bottom=iLow(_Symbol,0,2);
}
else if(dir<0)
{
top=iClose(_Symbol,0,2);
bottom=iHigh(_Symbol,0,2);
}
}
Do you need to draw a rectangle? Ok but how would you decide what is the time to stop drawing? Let us assume N bars to the right is enough, and let us ignore weekends for now(a bit more complicated if keeping in mind weekends when the market is closed).
bool drawRectangle(const int dir,const double top,const double bottom)
{
const datetime starts=iTime(_Symbol,0,2), ends=starts+PeriodSeconds()*N_bars;//time of start and end of the rectangle
const string name=prefix+"_"+(dir>0?"DEMAND":"SUPPLY")+"_"+TimeToString(starts);//name would be unique sinse we use time of start of the range. DO NOT FORGET about prefix - it should be declared globally, you would be able to delete all the objects with 'ObjectsDeleteAll()' function that accepts prefix in one of its implementations.
if(!ObjectCreate(0,name,OBJ_RECTANGLE,0,0,0,0,0))
{
printf("%i %s: failed to create %s. error=%d",__LINE__,__FILE__,name,_LastError);
return false;
}
ObjectSetInteger(0,name,OBJPROP_TIME1,starts);
ObjectSetInteger(0,name,OBJPROP_TIME2,ends);
ObjectSetDouble(0,name,OBJPROP_PRICE1,top);
ObjectSetDouble(0,name,OBJPROP_PRICE2,bottom);
//add color, width, filling color, access modifiers etc, example is here https://docs.mql4.com/ru/constants/objectconstants/enum_object/obj_rectangle
return true;
}
here is the main block, do not forget to add a new bar check, otherwise the tool would check for objects every tick which is waste of time. string prefix=""; //add some unique prefix for all your objects const int N_bars = 15; //15 bars in this example
void OnDeinit(const int reason){ObjectsDeleteAll(0,prefix);}
void OnTick()
{
if(!isNewBar())
return; //not necessary but waste of time to check every second
const bool pattern1Up=isPattern1Detected(1), pattern1Dn=isPattern1Detected(-1);
if(pattern1Up)
{
double top,bottom;
detectRangeOfZone(top,bottom,1);
drawRectangle(1,top,bottom);
PlacePendingOrder(1,top,bottom);
}
if(pattern1Dn)
{
double top,bottom;
detectRangeOfZone(top,bottom,-1);
drawRectangle(-1,top,bottom);
PlacePendingOrder(-1,top,bottom);
}
}
int PlacePendingOrder(const EnmDir dir,const double oop,const double suggestedSl)
{
const double lot=0.10; //FOR EXAMPLE, PUT YOUR DATA HERE
const string comment="example for SOF";
const int magicNumber=123456789;
int cmd=dir>0 ? OP_BUY : OP_SELL;
double price=(dir>0 ? Ask : Bid), spread=(Ask-Bid);
if(dir*(oop-price)>spread)
cmd+=(OP_BUYSTOP-OP_BUY);
else if(dir*(price-oop)>spread)
cmd+=(OP_BUYLIMIT-OP_BUY);
int attempt=0, ATTEMPTS=5, SLEEP=25, SLIPPAGE=10, result=-1, error=-1;
while(attempt<ATTEMPTS)
{
attempt++;
RefreshRates();
if(cmd<=OP_SELL)
{
price=dir>0 ? Ask : Bid;
result=OrderSend(_Symbol,cmd,lot,price,SLIPPAGE,0,0,comment,magicNumber);
}
else
{
result=OrderSend(_Symbol,cmd,lot,oop,SLIPPAGE,0,0,comment,magicNumber);

if(result>0)
break;
error=_LastError;
