[SalesForce] Trigger on A inserts B, Trigger on B inserts A – how to prevent errors

I have 2 triggers, one is on custom Order, other is on Opportunity. When I make both of them is active and try to run these objects, system gives error, how can I solve this problem? My triggers are:

trigger CreateaOpportunity on Order__c(after insert){ 
    if(trigger.IsInsert){
        List<Opportunity> OppList = new List<Opportunity>();
        for(Order__c OrderObj : Trigger.new){
            Opportunity Opp = new Opportunity();
            Opp.Name=OrderObj.Name+'-Opportunity';
            Opp.CloseDate=OrderObj.Close_Date__c;
            Opp.StageName=OrderObj.StageName__c;
            Opp.Orders__c = OrderObj.Id; 
            OppList.add(Opp);
        }
        if(OppList.size()>0)
        insert(OppList);
    }
}



trigger CreateOrder on Opportunity(after insert){
    if(trigger.IsInsert){
        List<Order__c> OrdList = new List<Order__c>();
        for(Opportunity OppObj : Trigger.new){
            Order__c Order = new Order__c(
            Name=OppObj.Name+'-Order',
            Close_Date__c=OppObj.CloseDate,
            StageName__c=OppObj.StageName,
            Opportunities__c=OppObj.Id
            );
            OrdList.add(Order);
        }
        if(OrdList.size()>0)
        insert OrdList;
    }
}

I get an error like this:
