_SS_:
tried it, it doesn't work!

Remove the semicolon in function declaration.

You have int First();

You need int First()

{

//-------- Function body ----------

return (0);

}

error

After adding a function to start(), there will be no warning

error

You don't need to describe it anywhere. It is not an error, but a warning that the function is not used anywhere in the EA and it can be removed.

After First(); function is called in the EA body, there will be no more such a warning.

Is there the smallest code that determines where the price is, above Moving or below it?

double MA1=iMA(Symbol(), Period(), PeriodMA, 0, MODE_SMA, PRICE_CLOSE, 1);

double pa=MarketInfo(Symbol(), MODE_ASK);

double pb=MarketInfo(Symbol(), MODE_BID);

int pt=MarketInfo(Symbol(), MODE_POINT);

int dg=MarketInfo(Symbol(), MODE_DIGITS);

---------------------------------------- Для Buy -------------------------------------------------

if(NormalizeDouble(pa, dg)>NormalizeDouble(MA1, dg)) {Price is higher than MA1}

if (NormalizeDouble(pa, dg)<NormalizeDouble(MA1, dg)) {Price is lower than MA1}

else if (NormalizeDouble(pa, dg)==NormalizeDouble(MA1, dg)) {Price is equal to MA1}

----------------------------------------------------------------------------------------------------

---------------------------------------- Для Sell ------------------------------------------------

if (NormalizeDouble(pb, dg)>NormalizeDouble(MA1, dg)) {Price is higher than MA1}

if (NormalizeDouble(pb, dg)<NormalizeDouble(MA1, dg)) {Price is lower than MA1}

else if (NormalizeDouble(pb, dg)==NormalizeDouble(MA1, dg)) {Price is equal to MA1}
