Good afternoon all! Please advise, there is a custom indicator, it has two objects. Their values I can find out, but here is no way to distinguish them, whether it is the top line or bottom. I can not know the number and order of the buffers, when installing there are no settings. On the Internet read that the settings for the colour also go as buffers, how to refer to them through the function iCustom () or maybe any other function to work out this point?
Thanks in advance!
P.S. Is there any literature on the MQL4 language? I've already downloaded and almost finished an MQL4 tutorial.
buffer numbers are counted from "0",
iCustom(NULL, 0, "ind",150, 0,2);
where 150 is the period,
0 is buffer,
2 is a bar.
https://docs.mql4.com/ru/indicators/iCustom
e.g.
#property indicator_buffers 2
#property indicator_color1 Blue
#property indicator_color2 Red
so most likely blue = 0 buffer
and red = 1
Alexander! Thank you for sharing your experience! But along the way I have a question, how is currency enumeration done? Or is it the name of the currency in the OrderSend() f-i in place of Symbol()? And could you please explain how to put your example in the code? Thanks again for your help! :)
Roman, basically explained.
Everywhere where Symbol() is specified in Expert Advisor, put for example: SymbolMax[nnnn]. In OrderSend(), it looks like thistick=OrderSend(SymbolMax[nnnn],OP_BUYSTOP,L,ur,0,sl,tp,CMM,MAGIC[I],0,Red);
I wrote it in my Expert Advisor, and you set your own values there. You can set the list of currencies, for example:
string SymbolMax[4] = {"EURUSD", "GBPUSD", "USDCHF", "USDJPY"};
Maybe, someone implemented it in another way but this is my currency lookup - see code below. I put start at the beginning of the function. Plus I've made a 5-second delay to prevent messages from jumping around.
I'm having a problem with a modification looping,
the modification is represented as a user defined function
The most interesting thing is that the standard trawl function works with both of these functions and i can do it alone ok, but when i use a fractal modification with breakeven, i get endless modifications with fractal and breakeven
I based it on the modification of https://book.mql4.com/ru/trading/ordermodify
I get the impression that the criterion for modifying Breakeven is not set correctly, how can I fix it to avoid looping?

Hello Dear forum users.
How can I request quotes from other timeframes? I have a template on D and my indicator needs quotes LOW, HIGH, OPEN, CLOSE from smaller timeframes (M30, H1, H4 for example).

Good evening all. tell me what is the error here. here is a piece of code.
//+------------------------------------------------------------------+

void start()
{
//---- check for history and trading

Пропущен символ ";"
thank you!!! Didn't notice at first.)))
Another question to the experts. how to enter correctly the opening condition: Close[2]<Close[3] by n percent for sell. for buy the opposite of course. and n can be optimized? thanks in advance!
void CheckForOpen()
{
double ma;
int res;
//---- go trading only for first tiks of new bar
if(Volume[0]>1) return;
//---- get Moving Average
ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0)
//---- sell conditions
if(Open[1]>ma && Close[1]<ma)
{
res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,0,0,",MAGICMA,0,Red);
return;
}
//---- buy conditions
if(Open[1]<ma && Close[1]>ma)
{
res=OrderSend(Symbol(),OP_BUY,LotsOptimized(),Ask,3,0,0,",MAGICMA,0,Blue);
return;
}
Tell me where i went wrong plz... or if it's MT4 itself, but my Buy orders open only on High bar, and Sell orders only on Close bar =) Although I haven't even stipulated these conditions in the Expert Advisor's code =)
