Getting Invalid Price error in Validation

[Takeshi Shibuki]

Hi, Im getting Invalid Price error in Validation to publish my EA.

Looking at this it looks like it's not getting the price.

My code regarding the order is below.

In fact, it is working normally in backtests and real trades.

Pls, somebody help me.

request.action = TRADE_ACTION_DEAL;
request.price = NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits);
request.sl = ask_stpls;
request.tp = ask_tkprft;
request.symbol = _Symbol;
request.volume = Lot;
request.magic = EA_Magic;
request.type = ORDER_TYPE_BUY;
request.type_filling = ORDER_FILLING_FOK;
request.deviation=5;

bool sent = OrderSend(request,result);

Tick size vs Point(), can be a little tricky in Multicurrency EA

Fernando Carreiro, 2022.03.09 12:11

Tick Size and Point Size can be very different especially on stocks and other symbols besides forex.

Always use Tick Size to adjust and align your prices, not the point size. In essence, make sure that your price quotes, are properly aligned to the Tick size (see following examples).

...
double tickSize = SymbolInfoDouble( _Symbol, SYMBOL_TRADE_TICK_SIZE );
...
double normalised_price = round( price / tick_size ) * tick_size;
...
// Or use a function
double Round2Ticksize( double price )
{
   double tick_size = SymbolInfoDouble( _Symbol, SYMBOL_TRADE_TICK_SIZE );
   return( round( price / tick_size ) * tick_size );
};

We are unable to see your full code, so we are unable to answer that.

For the "Instant Execution Policy", you always have to provide the price, as well as deviation if you want to control your re-quotes.

And remember that a Buy order opens at the Ask price, and a Sell order opens at the Bid price.

Just because your EA works in your environment, does not mean that it will pass the quality control of the validation process.

The validation process needs to make sure your EA will function correctly in other environments and with different contract specifications.

The users that will buy the product will certainly not have the same conditions as you.

Please, don't think only my poor knowledge fault easily.

This is an example of the part that executes a buy market order.

request.action = TRADE_ACTION_DEAL;
request.price = SymbolInfoDouble(_Symbol,SYMBOL_ASK);
request.sl = ask_stpls;
request.tp = ask_tkprft;
request.symbol = _Symbol;
request.volume = Lot;
request.magic = EA_Magic;
request.type = ORDER_TYPE_BUY;
request.type_filling = ORDER_FILLING_FOK;
request.deviation=50;
//--- send order
bool sent = OrderSend(mrequest,mresult);

Pls, look at 2nd line.

I can't get the Ask price from this function.

request.price = SymbolInfoDouble(_Symbol,SYMBOL_ASK);

Should I think this is a problem with other parts of my code?

look at error messages again.

I can't find any information to fix this problem in  The checks a trading robot must pass before publication in the Market

I tried to setting this to BID instead of ASK.(by BUY order)

request.price = SymbolInfoDouble(_Symbol,SYMBOL_BID);

So, Of course no transaction will take place.

I can understand about this result.I know.

However, the error message clearly changed.

just only one.

An error has occurred due to specifying the BID price in the buy order.

From this, it can be inferred that the BID price has been obtained.

"SymbolInfoDouble(Symbol(), SYMBOL_BID) " is looks working.

so, Why does  "SymbolInfoDouble(Symbol(), SYMBOL_ASK) " become zero? 

Can't this be considered a bug in the validator?

I just want help....

I could solved it.

Thank you Fernando.
