- Assess an indicator to test in case you ought to shut an order
- Update of take revenue and or cease loss costs
These are very frequent duties that many occasions will be achieved as soon as per candle when a brand new bar begins. Coding such a behaviour is just not arduous and solely requires just a few strains of code. We are going to see right here the required code.

You can see how removing all the comments you really only need a few lines
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | datetime NewCandleTime=TimeCurrent(); bool IsNewCandle(){ if(NewCandleTime==iTime(Symbol(),0,0)) return false; else{ NewCandleTime=iTime(Symbol(),0,0); return true; } } void OnTick(){ if(IsNewCandle()){ } } |
The logic of the script is:
- Create a variable and retailer the present server time
- Create a perform that checks the time and returns true if it’s a new candle and false if not
- Compare the beginning time of the final candle with the beginning time of the present candle
- If the time is identical then it’s the identical candle, whether it is completely different then we’re in a brand new candle
- If it’s a new candle return true and replace the time
- In the OnCalculate or OnTick perform use a if(IsNewCandle()){ } to execute the duty you need within the new candle
It is price remembering that the IsNewCandle() would return true each time the perform is initialized. For instance the primary time it runs or whenever you change the image or timeframe.
Conclusion of MQL4 On New Bar
As you’ll be able to see within the code above, checking if the candle is new is just not arduous in any respect. With only some adjustments you’ll be able to adapt the code to what you want. MQL4 On New Candle is easy and may resolve a number of complications.
If you wish to save hours of analysis and coding and also you wish to see some skilled code test this out! You can use it to construct your personal EA!
