Howto to get (current and last few bars) Price in mq4 EA

Hi!

This probably is a very basic question, but unfortunately all the EAs I have looked at, I can't find any example of getting the price of the instrument currently the EA is attached to. I also want to have price (High/Low/Open/Close) for some bar earlier e.g. last 10 bars.

Thanks in Advance.

Current bar price;

double OpenPrice=Open[0];
double ClosePrice=Close[0];
double HighPrice=High[0];
double LowPrice=Low[0];

Last bar price;

double OpenPrice=Open[1];
double ClosePrice=Close[1];
double HighPrice=High[1];
double LowPrice=Low[1];

etc............

For every backup in price you need to add [number] how long you want to look back.......
last say you want to look 10th bar before current one, you will code this;

double OpenPrice=Open[9];
.....the number 9 is ok becouse you are counting from zero bar (9+current bar is 10 bars)!!!

In most of the codes(especialy indicators) you will see ; double OpenPrice=Open[i];
take a note that you need to have initialized i ......int i; ...so i represents a zero bar!!!
For every bar back you want to look, just add u number to i...........

double OpenPrice=Open[i]; // CURRENT BAR
double OpenPrice=Open[i+1]; // LAST BAR
double OpenPrice=Open[i+2]; // CURRENT BAR-2
double OpenPrice=Open[i+9]; // CURRENT BAR-9
ETC..........

Thanks FOREXflash, much appreciated! exactly what I was looking for.

How can I know the high, close, open, low of a candle, using a vertical line, that when moving the vertical line gives the information of the candle?
I just have to recognize the sail on the line and give me the information about the sail. The error is red

#property indicator_chart_window extern color Ncolor=DeepPink; input ENUM_LINE_STYLE Style=STYLE_DOT; extern bool Alerta = True; extern bool Notifipush = True; int init() { return(0); } int deinit() { return(0); } int start() { ObjectCreate("0",OBJ_VLINE,0,Time[0],0); ObjectSet("0", OBJPROP_STYLE, Style); ObjectSet("0", OBJPROP_COLOR, Ncolor); datetime line0 =ObjectGetValueByShift("0", 0); double open=Open[line0]; double close=Close[line0]; double high=High[line0]; double low= Low[line0]; string comentario = ""; comentario = comentario +" "+"RETROCESO"+"\n"; comentario = comentario +" "+" "+"OPEN."+" "+"+"+open + "\n"; comentario = comentario +" "+" "+"CLOSE."+" "+"-"+close+ "\n"; comentario = comentario +" "+" "+"HIGH."+" "+"-"+high+ "\n"; comentario = comentario +" "+" "+"LOW."+" "+"-"+low+ "\n"; Comment(comentario); return(0); }

All you need is a time of the vertical line and then use that time to get the bar at that time (using iBarShift(NULL,0,TimeOfVerticalLine))

I tried as you told me but it does not work well, I attach the indicator, I just need to drag the line in the different candles and this has to give me the information of the candle. The only thing I need is to get the values of the candle from the vertical line.

Hello,

A simple question as I'm a bit confused..

If Close[0] returns the close price of the current bar, wouldn't it also be the same as the bid price(in the case that the chart is drawn by the bid price)?

And if so, if I'm looking for a certain candle type like a Hammer candle, I would have to check the previous bar's - [1] prices and not the current one's?
Since the current candle has not yet taken it's final shape.

Very helpful code, I my case I want to compare price of the last 4 closed candles. if the close price of the latest closed candle is higher than the previous 3 then an alert must be sent to the Mobile MT4 platform.
my script is as follows but it does not give me expected result. What is the problem?
void CalculateHighestclose()
{
int highestcdl=0;
double closeprice=0;
for (int i=4;i>=1;i--)
{
if (Close[i]>highestcdl) highestcdl=i;
}
// alert trigger condition is met if candle 1 has the highest closing price
if (highestcdl==1)
{
// Logic to send the alert to mobile MT4 goes here
// I need help with the logic as well
}
}
