MT5 error 10021: There are no quotes to process the request
Add the symbol to Market Watch with SymbolSelect(), make sure SymbolInfoTick() returns a price, and try again on the next tick.
Updated 22 October 2026. Runs in your browser; nothing you type is uploaded.
The number after retcode= in MT5's Experts or Journal tab. 41 codes, as MQL5's reference words them.
What MQL5 says
10021TRADE_RETCODE_PRICE_OFF- There are no quotes to process the request
From MQL5's table of trade server return codes, read 22 October 2026. An Expert Advisor finds it in MqlTradeResult.retcode; the Experts and Journal tabs print it.
What causes it
The server has no current price for the symbol to fill against: the symbol is not in Market Watch, no tick has arrived yet, or the market is not quoting.
The fix in MQL5
Add the symbol to Market Watch with SymbolSelect(), make sure SymbolInfoTick() returns a price, and try again on the next tick.
#include <Trade/Trade.mqh>
CTrade trade;
void OpenBuy(const string symbol, const double lots)
{
trade.Buy(lots, symbol); // a symbol that is not in Market Watch
}#include <Trade/Trade.mqh>
CTrade trade;
void OpenBuy(const string symbol, const double lots)
{
if(!SymbolSelect(symbol, true)) // add it to Market Watch so quotes flow
return;
MqlTick tick;
if(!SymbolInfoTick(symbol, tick) || tick.ask == 0.0)
{
Print(symbol, ": no price yet, try again on the next tick");
return;
}
trade.Buy(lots, symbol, tick.ask);
}Both compile in MetaEditor 5 with no errors or warnings. Adapt them to your EA; they were not run against a trade server.
