Guys, please i need help with this MT4 error message: 'SYMBOL_TRADE_ALLOWED' - undeclared identifier

The code is below;

// Function to start multi-pair trading
void StartMultiPairTrading() {
// Split the SymbolsToTrade string into an array
string symbolArray[];
int totalSymbols = StringSplit(SymbolsToTrade, ',', symbolArray);
// Loop through each symbol in the array
for (int i = 0; i < totalSymbols; i++) {
// Check if the symbol is in the Market Watch AND trading is allowed
// (Checking for SYMBOL_TRADE_MODE is essential)
if (SymbolInfoInteger(symbolArray[i], SYMBOL_TRADE_ALLOWED) == 1 && SymbolInfoInteger(symbolArray[i], SYMBOL_TRADE_MODE) == 1) {
// Do something with the symbol
// Example: Print the symbol name to the log
Print("Trading symbol: ", symbolArray[i]);
// Calculate indicators for the current symbol
CalculateIndicators(symbolArray[i]);
// Manage trades for the current symbol
ManageTrades(symbolArray[i]);
} else {
// The symbol is not in the Market Watch or trading is not allowed
Print("Symbol not found in Market Watch or trading is not allowed: ", symbolArray[i]);
}
}
}

Thaaank you very much sir, I think that will get the job done, Your work has been incredibly valuable to me,it would be immensely helpful if you make an mt 5 version of it, I understand that this may require some additional effort, and I truly appreciate your time and expertise in making these adjustments.Thank you very much for your support and for your continued excellent work.
Hi Coders, can someone please have a look at the attached EA. When it trades it opens orders 0.01, 0.06 then 0.31. That is way to big. Is it possible to code in a multiplier which can be set to a specific value or can the lots be made to grow in sequence as 0.01, 0.02, 0.03, 0.04 etc. Any help much appreciated. Thank you

hi all again, the worst version was blended 9, it was mixed with a repainting indicator. this version test9.7 should be the last version i can make ok without filtering. this indicator is at its testing phase only so, 48 hours would be more than enough for anyone wanting to check even though obviosly i allow more than 48. anyone wants to have unlimited version should please explain how exactly the indicator is profitable like 3 people already got version 7 and 8. i might spare time to read any constructive feed backs. ps. i forgot to remove...

Got SL.
If I had been observing, not sleeping, I would have closed on the Bullish signal and gone Long.
And, consistently, I would have had to open Short on the new Bearish signal.
The question remains, would I have made a profit on the Long?
Would I have made more profit on the Long than I had lost?
Or, would I have had another SL?
I will say, that more likely than not, I would have had another SL, because the price would not have reached my TP...

So, my point is not that this indicator is bad, or good.
My point is that there is no indicator or strategy which guarantees TP and not SL.
And only the trader can tip the scales in their favor.

And also, it always looks good on the historical charts.
Problem is, we can't make money by trading historical charts.
Scammers can make money by selling ideas based on the historical charts, and that's the sad thing.

In MQL4 there is no such identifier as SYMBOL_TRADE_ALLOWED.

In MQL5 there is no such identifier as SYMBOL_TRADE_ALLOWED.

If you want to code, you need to read the book and documentation.

if you are seeking my personal way to put SL for this particular indicator
please look at the white boxes i put with clear fractal highs/ lows but if you have a system which gives you the direction then you can only take trades for one direction at a time.

Well, in the case of the SL trade, that's how my SL was placed!

It's not about how to place the SL.
It's about when to close profit, if the profit is there.
Even if we have the SL placed "correctly", we can still get it because the price never reached the TP.
And that is the whole problem with trading!

You see, reality is that in total RR must be on our side in order to make profit.
And also, reality shows that RR is impossible to achieve in any reasonable, predictable way.
It seems like the only way to get RR is to break the rules and go heavy when the price is moving strongly.
That's why there are no rules, here.

And, again, you are showing the past...
It is easy to give "good" advice on historical charts!

i was only giving my way for putting sl because you are talking about your sl is gone.
with new picture i can see that there is an opposite signal before your sl if you had not taken profit. but look that is not my business here, that is completely different thing. all i m doing here is trying to see if my testing indicator is any good in anyways. now i shall stop it here, no further versions, i want you remain in peace, period.

That's how the current Long would have to look like in order to get proper RR.
Do you think that this scenario has any chances of coming to past?

Yes, your indicator is both good and not good.
It may sound illogical, but it is true, because any indicator is only an indicator.
It is neither good nor bad - it is what it is.
The indicator does not make money!
Unless you sell it to ignorant people!

A truely good indicator would be one that showes us the following before the fact:
1. Entry price,
2. SL price,
3. TP price,
4. All above with RR more than 1,
5. The win ratio of this indicator must be minimum 50% and more.

BTW, I do like the channel!
So, maybe we can get an unlimited version so that we can have the channel?

Can You provide such an indicator?

Hi Bestie

The below code work fine but not with property strict

2 errors - k is undeclared and implicit number to string

I tried to fix but then it doesn't show anything on chart

Any solution?

Thanks in advance

for (int k = i; k<Bars-1; k++) if (state[k]!=state[k+1]) break;
string name = UniqueID+":"+Time[k];
datetime lastTime = Time[i];
ObjectDelete(name);
ObjectCreate(name,OBJ_RECTANGLE,0,Time[k+1],0,lastTime,WindowPriceMax()*3.0);
ObjectSet(name,OBJPROP_BACK,true);
if (state[i]==-1)
ObjectSet(name,OBJPROP_COLOR,ColorDown);
else ObjectSet(name,OBJPROP_COLOR,ColorUp);

Where is the rest of the code?
This snippet on its own can not work because there are variable values missing.
So, I need the whole code in order to see what's going on.

{quote} Why aren't you using this one? {file} And why are you using 6 & 6? That makes zero sense. The idea is to get a picture like this: {image} And you don't get that with 6 & 6. You need to adjust the indicator to the market (candles). The indicator can not adjust itself! And another thing: It is also useless to measure over 500 candles. We can not trade the past, so we need to model the recent Price Action only.
