What is the difference between POINT and TICKSIZE ? When you query through MarketInfo() they are the same, but why should they be different if they have different names?

Sometimes they are different for individual instruments

Thank you. A point is like a penny-unit of measure. Tixais is the minimum change in price. Apparently tixies can't be less than a pip and more. I guess it is up to the BC to decide.
 
Can you please tell me if it is possible to run a macro from MQL in an EXCEL book (it is open)?

How do I calculate the maximum allowable lot size with leverage etc.?
Thank you
double MeansOneLot       = MarketInfo(Symb,MODE_MARGINREQUIRED);      //Необходимо средств для открытия 1 лота
double MeansFree         = AccountFreeMargin();                       //Значение свободных средств, разрешенных для открытия позиций
double MeansGuaranty     = AccountMargin();                           //Значение залоговых средств, используемых для поддержания открытых позиций
double LotPriceTic       = MarketInfo(Symb, MODE_TICKVALUE);          //Стоимость 1 лота в валюте депо на 1 тик
double MaxLotPermissible = MathFloor((MeansFree/MeansOneLot)*100)/100;//Максимально допустимый лот для открытия позиции
 
joo:

Thank you very much.
 

HELP TO ATTACH THE FILE TO THE TEXT

 
Friends, help me solve a problem... I have ticket numbers written to TicketArray array (there are 3 of them). So, I want my EA to stop trading when I get a loss 3 times in a row... For starters, I cannot write the condition of 3 lots... The Good Serpent once gave me some knowledge about flags and I am using them now, but it still does not work. After the first order closes in loss, it turns true, and then it works fine... Why?

bool flag = true; //по умолчанию флаг стоит на правду
for(int j=1;j<4;j++) //цикл из 3х значений (1,2,3)
{
OrderSelect(TicketArray[j],SELECT_BY_TICKET); //выбираю ордер

if(OrderClosePrice()!=OrderStopLoss() && TicketArray[j]==0)flag = false; //думаю, тут проблема. Условие: если ордер не получил лося 3 раза и если у тикета еще нет номера, то такая ситуация меня не устраивает.
Print(OrderClosePrice(),",,,,,",OrderStopLoss(),",,,,,",TicketArray[j]); //эта строчка для тестера, чтоб наглядно было видно цену закрытия, цену стопа и номер тикета. Хоть тикет и =0, но все равно пишет true.
}
Alert(flag);

I am pasting the entire EA just in case. This is an ordinary martingale, which I wrote myself for educational purposes.

Can't read one of the PerkyAsctrend1 indicator buffers.
Please help me to figure it out. I have done it many times with other indicators, always without problems. I cannot do it here.
I read two buffers: one of them:
double PerkyBuf2=iCustom (NULL,0," PerkyAsctrend1 ",5,250,0,1); - reads correctly, the signal is caught, next line tries to catch:
double PerkyBuf1=iCustom (NULL,0," PerkyAsctrend1 ",5,250,1,1); but all signals in this buffer are flying past my EA. I even tried to create an empty Expert Advisor with two Comment() points with results. I cannot get a signal for sell.
Can you help me understand it.
I would like to attach indicator

Signal for Buy in buffer 0, signal for Sell in buffer 1
