Hello. Please advise how to prescribe in the code of MQL4 EA the rule of opening an order: there should be an order with a certain magic number in the market; if there is no such order, the EA does not open anything according to its main algorithm.
That's about as far as it goes:
{
Comment( IsCount(ORDER_TYPE_BUY_STOP, 5) ); // type - тип, mg - magic
}
//------- Вернёт количество
int IsCount(int type, int mg) {
int p=0;
for(int i=0; i<OrdersTotal(); i++) {
if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
if(OrderSymbol()==Symbol() && OrderMagicNumber()==mg) {
if(OrderType()==type) {
p++;
}}}}
return(p);
}
How do I make it possible for a user to fill an array?

Greetings, there is an indicator that draws the order history on the chart, code:

Single trades the indicator draws correctly (line>background>profit), but in the display of closed order sets there is a small "bug" (screenshot attached), lines are superimposed on the background and profit (line(1)>background>profit>line(2)>line(3)>line(4) . . . . ).
It should be as follows: (line(1)>line(2)>line(3)>line(4) . . . >fon>profit). Various tampering has not been successful, please help me to fix it.
Who else can fill it in except the user?
I mean how to fill it in via settings. Let's say through a string, and then put its value into an array...

That's about as far as it goes:
{
Comment( IsCount(ORDER_TYPE_BUY_STOP, 5) ); // type - тип, mg - magic
}
//------- Вернёт количество
int IsCount(int type, int mg) {
int p=0;
for(int i=0; i<OrdersTotal(); i++) {
if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
if(OrderSymbol()==Symbol() && OrderMagicNumber()==mg) {
if(OrderType()==type) {
p++;
}}}}
return(p);
}
That's about as far as it goes:
void OnTick()
{
Comment( IsCount(ORDER_TYPE_BUY_STOP, 5) ); // type - тип, mg - magic
}
//------- Вернёт количество
int IsCount(int type, int mg) {
int p=0;
for(int i=0; i<OrdersTotal(); i++) {
if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
if(OrderSymbol()==Symbol() && OrderMagicNumber()==mg) {
if(OrderType()==type) {
p++;
}}}}
return(p);
}
Примерно так можно:
{
Comment( IsCount(ORDER_TYPE_BUY_STOP, 5) ); // type - тип, mg - magic
}
//------- Вернёт количество
int IsCount(int type, int mg) {
int p=0;
for(int i=0; i<OrdersTotal(); i++) {
if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) {
if(OrderSymbol()==Symbol() && OrderMagicNumber()==mg) {
if(OrderType()==type) {
p++;
}}}}
return(p);
}
Спасибо большое, попробую.
It's kind of like this.
Thank you!
ORDER_TYPE_BUY_STOP is highlighted in MQL4 Editor, but not in MQL4 Help. Question: does it work in MQL4, it corresponds to OP_BUYSTOP type ? I just don't have time to check it yet.
Yes, it works 100%, it's the only way I'm writing now. Now a lot of things have migrated from Five to Four.
Even this one works, though the compiler used to swear it was a trend line
ObjectSetDouble(chart_ID,nm,OBJPROP_PRICE,p1);
ObjectSetInteger(chart_ID,nm,OBJPROP_TIME,1,t2);
ObjectSetDouble(chart_ID,nm,OBJPROP_PRICE,1,p2);
