Hello all, I am writing code for a trawl of group orders . The code logic for a trawl is as follows :

Under what conditions should the trawl for group orders start?

Hello all, I am writing code for a trawl of group orders . The code logic for the trawl is as follows :

  int order[]={1,2,3,4,5,6,7,8,9,10};



void Tral_BU_Stop() {
 
  int j;
  for (int i=OrdersTotal()-1; i>=0; i--) {
  if (OrderSelect(i, SELECT_BY_POS,MODE_TRADES)==True){
  if (OrderMagicNumber()==Mg&&OrderSymbol()==Symbol()&&OrderType() ==OP_BUYSTOP){
  j++;
  if ( Bid<=OrderOpenPrice()-DistPoint*order[j]*Po){
  bool modb=OrderModify(OrderTicket(),Bid+(DistPoint*order[j])*Po,OrderStopLoss(),OrderTakeProfit(),0,clrGreen);}} }}}
//================
  void Tral_SEL_Stop() {
  
  int j;
  for (int i=OrdersTotal()-1; i>=0; i--) {
  if (OrderSelect(i, SELECT_BY_POS,MODE_TRADES)==True){
  if (OrderMagicNumber()==Mg&&OrderSymbol()==Symbol()&&OrderType() ==OP_SELLSTOP){
  j++;
  if (Ask>OrderOpenPrice()+DistPoint*order[j]*Po){
  bool mods=OrderModify(OrderTicket(),Ask-(DistPoint*order[j])*Po,OrderStopLoss(),OrderTakeProfit(),0,clrRed);}} }}} 

Change the values and you will be happy

Change the values and you'll be happy, I think you'll figure it out

What is "Ro"?

DistPoint*order[j]*Po

Point.

In this case, when the second order is opened, a stop-loss order will be placed and there may be no possibility to open the third order in the grid...

I meant under what conditions it starts

TrailingGroupOrder()

As far as I know, you cannot place a stop before the order is opened

and there is no way to do group modification without it

j++;
  if (Ask>OrderOpenPrice()+DistPoint*order[j]*Po){
  bool mods=OrderModify(OrderTicket(),Ask-(DistPoint*order[j])*Po,OrderStopLoss(),OrderTakeProfit(),0,clrRed);}

Why this duplication

You can do it like this.

And also show me what parameters

You're right, Makar, but most of this code isn't mine. I took it from a self-study book. All the more so, this substitution doesn't solve the question at hand.
