7 parameters is not an option) 7 names of horizontal lines in the parameters that it will draw and name. And we should proceed from them. And if the parameters, the range of price movement and the number of levels. Calculate and draw. Well, when the level triggers, it should draw the sl line and if the sl coincides with the price level, it should change its colour.

You kind of need an algorithm that draws lines at the calculated prices.

When all the positions are closed, they should be deleted.

Clarification:

В настройках трал 30. Значит показать линии на уровнях, где сработают тралы, и так все 7 линий: 30-60-90-120-150-180-210, типа прогрессии.

Прошли 30 и достигли линии, трал переводит стопы на уровень цены открытия, по достижении 60, переводит стопы на +30 от цены открытия, то есть на уровень, где срабатывал первый стоп и тд.

Change the code, draw lines and nothing else.

Thank you!

Good afternoon. Well advise a newbie, trying to upload an expert in the market. Gives error "Error! Wrong type of file uploaded, .....ex4 - Script.
Your product category - Experts, the correct program type for it - Expert" But it is an Expert! Where do I dig? I`ve been struggling for 2 days!

Dig towards the standard handlers.

I'm sure you have start() there, not OnStart().

When all positions are closed, they should be deleted.

double sumLots[2]=0,weight[2]=0;

for(int pos=OrdersTotal()-1;pos>=0;pos--) {

   if (! OrderSelect(pos,SELECT_BY_POS,MODE_TRADES)) continue;

   // тут всякие прочии фильтры

   DrawOrderLevels(); // нарисовать уровни куда может перекатиться стоп-лосс конкретного ордера

   // расчёт общих позиций

   int type=OrderType();

   sumLots[type]+=OrderLots();

   weight[type]+=OrderLots()*OrderOpenPrice();

}

double avg[3]; // общии позиции

if (sumLots[OP_BUY]!=0) avg[OP_BUY]=weight[OP_BUY]/sumLots[OP_BUY]; 

if (sumLots[OP_SELL]!=0) avg[OP_SELL]=weight[OP_SELL]/sumLots[OP_SELL]; 

// совокупная позиция

int posType; // тип

double posPrice; // цена

double posLots; // объём

if (sumLots[OP_BUY]>sumLots[OP_SELL) { posType=OP_BUY; posPrice=avg[OP_BUY]; posLots=sumLots[OP_BUY]-sumLots[OP_SELL]; }

else { posType=OP_SELL; posPrice=avg[OP_SELL]; posLots=sumLots[OP_SELL]-sumLots[OP_BUY]; }

DrawPriceLevels(OP_BUY,avg[OP_BUY]); // нарисовать уровни суммарной позы в BUY

DrawPriceLevels(OP_SELL,avg[OP_SELL]); // нарисовать уровни суммарной позы в SELL

DrawPriceLevels(posType,posPrice); // уровни общей позиции

In the names of horizontal levels add the ticket number. Sometimes (when necessary) to check - if the ticket is not in the market, then all levels with its name should be removed

Artyom you are already tired and have started to make inaccuracies yourself. For the expert that Vyacheslav is trying to load, the event handling function should be OnTick()

Yes, you're right. My mistake. Of course it was about OnTick()
