Ошибка 130 mt4

Как уже написали — TP забыт

Ticket=OrderSend(Symb,OP_SELL,Lots,Bid,3,SL, TP, Green); //открытие Sell
Но видимо проблема не в этом?

Я сделал так

sl1 = NormalizeDouble(Bid + MLockSL * Point,Digits);
if (MLockSL <= 0) sl1 = NormalizeDouble(0,Digits);
tp1 = NormalizeDouble(Bid - MLockTP * Point,Digits);
if (MLockTP <= 0) tp1 = NormalizeDouble(0,Digits);

Balancelots = NormalizeDouble(Balancelots,Digits);

Comment ("155: Balancelots=",Balancelots);
Alert ("155: Пытаюсь залочить buy! Balancelots=",Balancelots," SL1=",sl1," TP1=",tp1);

LockTicketB=OrderSend(Symbol(),OP_SELL,Balancelots,Bid,Slippage,sl1,tp1,"225:залочили buy",362,0,Magenta); // лочим buy

if(LockTicketB<0)
     {
      LockBuy =0;
      Print("165: Не смог залочить buy ",ErrorDescription(GetLastError()));
      Alert ("165: Не смог залочить buy! Balancelots=",Balancelots," SL1=",sl1," TP1=",tp1,"Bid=",Bid);
     }
     else
     Alert ("166: Залочил buy! Balancelots=",Balancelots," SL1=",sl1," TP1=",tp1,"Bid=",Bid);

You should know that there exists a minimum Stop Loss Size (mSLS) given in pips. «mSLS» changes with the currency and broker. So, you need to put in the OnInit() procedure of your EA a variable to get it:

int mSLS = MarketInfo(symbol,MODE_STOPLEVEL);

The distance (in pips) from your Order Open Price (OOP) and the Stop-Loss Price (SLP) can not be smaller than mSLS value.

I will try to explain a general algorithm I use for opening orders in my EAs, and then apply the constrain on Stop-Loss level (at step 3):

Step 1. I introduce a flag (f) for the type of operation I will open, being:

f = 1 for Buy, and
f = -1 for Sell

You know that there are mql4 constants OP_SELL=1 and OP_BUY=0 (https://docs.mql4.com/constants/tradingconstants/orderproperties).

Once I have defined f, I set my operation type variable to

int OP_TYPE =  int(0.5((1+f)*OP_BUY+(1-f)*OP_SELL)); 

that takes value OP_TYPE=OP_BUY when f=1, while OP_TYPE=OP_SELL when f=-1.

NOTE: Regarding the color of the orders I put them in an array

color COL[2]= {clrBlue,clrRed};

then, having OP_TYPE, I set

color COLOR=COL[OP_TYPE];

Step 2. Similarly, I set the Order Open Price as

double OOP =  int(0.5*((1+f)*Ask+(1-f)*Bid));

which takes value OOP=Ask when f=1, while OOP=Bid when f=-1.

Step 3. Then, given my desired Stop Loss in pips (an external POSITIVE parameter of my EA, I named sl) I make sure that sl > SLS. In other words, I check

if (sl <= mSLS) // I set my sl as the minimum allowed
  {
    sl = 1 + mSLS;
  }

Step 4. Then I calculate the Stop-Loss Price of the order as

double SLP =  OOP - f * sl * Point;

Step 5. Given my desired Take Profit in pips (an external POSITIVE parameter of my EA, I named tp) I calculate the Take-Profit Price (TPP) of the order as

double TPP =  OOP + f * tp * Point;

OBSERVATION: I can not affirm, but, according to mql4 documentation, the minimum distance rule between the stop-loss limit prices and the open price also applies to the take profit limit price. In this case, a «tp» check-up needs to be done, similar to that of the sl check-up, above. that is, before calculating TPP it must be executed the control lines below

if (tp <= mSLS) // I set my tp as the minimum allowed
  {
    tp = 1 + mSLS;
  }

Step 5. I call for order opening with a given lot size (ls) and slippage (slip) on the operating currency pair (from where I get the Ask and Bid values)

float ls = 0.01;
int slip = 3; //(pips)

int order = OrderSend(Symbol(),OP_TYPE,ls,OOP,slip,SLP,TPP,"",0,0,COLOR);

Note that with these few lines it is easy to build a function that opens orders of any type under your command, in any currency pair you are operating, without receiving error message 130, passing to the function only 3 parameters: f, sl and tp.

It is worth including in the test phase of your EA a warning when the sl is corrected for being less than the allowed, this will allow you to increase its value so that it does not violate the stop-loss minimum value rule, while you have more control about the risk of its operations. Remember that the «sl» parameter defines how much you will lose if the order fails because the asset price ended up varying too much in the opposite direction to what was expected.

I hope I could help!

What is MT4 error 130?

The MT4 error 130 is an OrderSend error code of the MetaTrader 4 platform. A trading platform shows this error code when an Expert Advisor fails to execute an order according to expectations. This error is also known as invalid stops.

An OrderSend error can be very crucial for the day traders because their timing of market entry and exits are equally important. Also, such errors may damage your profit factors and heavily affect your risk to reward ratio.

In this article, we will discuss when an MT4 error 130 happens and how to fix this issue ensuring a smoother trading experience.

Why does MT4 error 130 happen?

An MT4 error 130 may occur for the following reasons:

Market orders

While opening a buy or sell order if you set the stop-loss and take profit levels closer to the market price, the MT4 platform will not accept the order. Instead, it will show your the error code 130.

For direct buy orders, if your stop-loss limit is greater than the asking price and the take profit level is lower than the bidding price, the MT4 will still show the OrderSend error code. On the other hand, for market sell orders, an error code 130 appears when the stop-loss level is lower than the bidding price and the take-profit level is higher than the asking price.

Pending orders

An error code130 may also appear during placing a buy limit and buy stop order. It happens when the difference between the asking and the entry price or the difference between the entry and take profit price is less than the stop-loss limit.

For sell limit and sell stop orders, the OrderSend error occurs if the difference between the bidding and entry price or the difference between the entry and take profit price is less than the stop-loss level.
