MQL5 When Stop Loss is hit, wait for MACD to cross 0

 

Hi,


I have an EA working but I cannot seem to find a way to do the following:

1. Only have one trade at all times

2. When the stop loss is hit, wait for the MACD indicator to cross 0


Any advice/help would be amazing, I've been trying to find a way for weeks!

All the best,

Martin

 
int ordersmax=1;
if(OrdersTotal()<ordersmax)
 {
  // Order...
 }

then combine.

if(OrdersTotal()<ordersmax)
 {
  if(macd crossed 0)
   {
    // Order...
   }
 }

Hi Martin,

the stop-loss is handled at the server side (the broker). You have no control over how it is handled, even not with an EA. When the stop loss is hit, the order will be closed, period. Although you may not realize it, or think this is not what you want, this is actually what stop loss is meant to do. It's a safeguard against al kinds of disasters that you, the EA or your internet connection might trigger.

What you probably want is a controlled exit out of a trade once a certain negative value is hit. Such a controlled exit should be handled on your trading platform (and not on the brokers server as a stop loss). Indeed, something you would use an EA for. If your EA doesn't support this then your options become limited (if it is an EA that you bought or downloaded).

If you are writing the EA yourself then you could do something like this (pseudo code):

1) Set a static variable:
bool low_limit_reached = false;
bool macd_cross_detected = false;

2) Keep track of the current profit (in pips) of your trade:
double profit = (CurrentPrice - OpenPrice)/Points (for SELL);
                        (OpenPrice - CurrentPrice)/Point (for BUY)

3) When profit falls below a certain treshhold, you set:
if (profit < -30.0) low_limit_reached = true;

4) Check if the MACD has crossed 0:
if (iMACD(,,,0) > 0 && iMACD(,,,1) < 0) macd_cross_detected = true; // once for SELL and once for BUY

5) Check if both conditions are true:
if (low_limit_detected && macd_cross_detected) OrderClose();

The code is very rough and just indicative of how you could solve it. But it should give you an idea on how to proceed.

Succes with your trading!

Thank you very much for your replies!

I have my stop losses already coded as well as the MACD cross (only for entries).

Here's my code, I added openlong and openshort booleans to detect whether a long/short has already been placed (in the "Try to open a deal" section. For example, if it enters a long, it will set openlong to true and will not take a long position until it opens a short. I want it to do this only when the stop loss is hit.

Any idea what I am missing?

All the best,

Martin

Thank you very much for your replies!

I have my stop losses already coded as well as the MACD cross (only for entries).

Here's my code, I added openlong and openshort booleans to detect whether a long/short has already been placed (in the "Try to open a deal" section. For example, if it enters a long, it will set openlong to true and will not take a long position until it opens a short. I want it to do this only when the stop loss is hit.

Any idea what I am missing?

As @Twan Jansbeken mentioned, you'll have to keep track of your stop loss prices locally, without making calls to ext_trade.PositionModify in your ModifyOrders function.

Also, these lines contain bug and your openlong and openshort flags get set to false erroneously:

   if((shortema1 > longema1) && (openlong = false))
   :

   if((shortema1 < longema1) && (openshort = false))
   :

As @Twan Jansbeken mentioned, you'll have to keep track of your stop loss prices locally, without making calls to ext_trade.PositionModify in your ModifyOrders function.

Also, these lines contain bug and your openlong and openshort flags get set to false erroneously:

Let me summarize what @Twan Jansbeken explained: it would close a position if open p&l is, say, -$30 AND if the MACD crosses 0. Am I correct?

However, I want the EA to stop trading until the MACD crosses 0 again when the stop loss is hit. Wouldn't the openlong/openshort statement do the job?

I realized that my openlong and openshort are in the wrong place. They should be in the ModidyOrders function.


Also, I put the lines @Marco vd Heijden wrote around the following but it is not doing anything. I declared it as "int  ordermax  = 1" at the beginning of the code; Any ideas?

 //to open long position
   if(OrdersTotal()<ordermax)
   {
   if((shortema1 > longema1) && (openlong = false))
   {
   if(stochastic_k_line[1]>20 && stochastic_k_line[2]<=20)
   {
   
   openlong = true;
   openshort = false;
   
       Alert("Open long position, because k stochastic enters 0;20 zone");
       Print("Try to open long for ",_Symbol);
       OpenPosition(arr_ticket_long_stochastic,ORDER_TYPE_BUY);
      return;
   }
   }

   //check condition "Stochastic indicator (%K line) leaves the 80-100 zone"
   //to open short position
   if((shortema1 < longema1) && (openshort = false))
   {
   if(stochastic_k_line[1]>80 && stochastic_k_line[2]<=80)
   {
   
   openlong= false;
   openshort = true;
   
       Alert("Open short position, because k stochastic leaves 80;100 zone");
       Print("Try to open short for ",_Symbol);
       OpenPosition(arr_ticket_short_stochastic,ORDER_TYPE_SELL);
      return;
   }
   }
   }

Sorry, I misunderstood your requirements earlier. So ignore what I said about changing your ModifyOrders function with regard to stop loss settings.

Now, to do the stop trading until MACD crosses 0 part, I suggest instead of having openlong and openshort, just have one named MACDCut. Set it to true when (1) there is no trade, and (2) there's a zero crossing. Then open a new order only when MACDCut is true (plus your original stochastic conditions), but right after opening, set it to false.

And btw, double check this line - looks wrong:

if(stochastic_k_line[1]>80 && stochastic_k_line[2]<=80)

Thanks @Seng Joo Thio for pointing out the line, I corrected it.

The issue with this is that in a bullish MACD trend, for instance, the system will only take one position regardless of the number of long opportunities, until MACD crosses 0. I would like it to just stop trading after the stop loss was hit and then start again after a MACD zero cross.

Do I need to use HistoryDealSelect and then OnTradeTransaction?

I'm thinking of have a line with if(OrderClosePrice() = OrderStopLoss()), then MACDcut = true. Is there a more efficient way?

Hmm... that seems unnecessary, unless I misread your words again (LOL).

This algorithm (same as what I described earlier) should suffice:

        if (MACD Crosses zero && there is No On-going Trade)

                MACDCut = true

        if (MACDCut==true) {

                if (Buy condition satisfied) {

                        Open New Buy

                        MACDCut = false

                }

                if (Sell condition satisfied) {

                        Open New Buy

                        MACDCut = false

                }

        }

        // Do other stuff like trailing stops, etc.


Only slight tweaking, in future, if you decided to open more than one trade at one time...

Yes but when the next stop loss is hit, it will continue opening trades until the MACD crosses 0 again.

That's what I am trying to do:

If Stop Loss is hit, then stop trading until MACD crosses 0 again.

Once the MACD crosses 0, MACDCut is reset.


Do you know how I can determine that the Stop Loss was hit?
