Horizontal Lines change colour automatically

Hi,

I wonder if possible to code an indicator that will change the colour of manually drawn horizontal lines automatically, to detect when the current price is
above or below them ?

Would be a nice solution to spot when support becomes resistance & vice versa.

Thanks.

Yes it is possible.

You can iterate over all drawn objects on the chart using ObjectTotal and a for loop and compare the OBJPROP_PRICE1 value to the current close price. If the price is above/below the price you can set the color using ObjectSet.

Can anyone code this indicator only for manually drawn horizontal lines ?

Thanks.

Hey, am also looking for same thing but came across this at MQl5. The only problem is that it draws a single horizontal line, if someone can rectify the code and have it draw more SR horizontal line.

I don't have mt 4 installed anymore so I can just give it a shot without trying it. If you only want manually drawn lines you have to check the name of the lines. This can't be easily done without tampering with the code of the other indicators or ea's. Or you rename your manually lines accordingly and check for that.

A snippet which takes care of the color change
Inserted Code
 
color[] col = {someColor,someOtherColor};
 
for(int i = 0; i < ObjectsTotal(); i++){
    string objName = ObjectName(i);
 
    if(ObjectType(objName) == OBJ_HLINE){
           double price = ObjectGet(objName,OBJPROP_PRICE1);
           ObjectSet(objName,OBJPROP_COLOR,col[price > Close[0]]);
    }
}

Basically, I would draw all lines that I identify as support & resistance manually.

I would choose a colour for Resistance Lines (above bid current price) and a colour for Support Lines (below current bid price).

All lines above current price will change to auto resistance colour and all lines below to auto support colour ( change automatically).

Lines will automatically change colour as price moves through these lines.

It should pick up all horizontal lines and colour them accordingly.

This indicator would be perfect if it allowed you to draw more than a single line.

Try the attached.

Set ManualLineColor to the color of the manual lines plotted. (I don't know how to have MT4 recognize whether a line has been plotted manually or automatically, hence you'll need to set all manual lines to the same specified color, to set them apart).

I have had a quick look at the code and it appears that it does draw multiple lines but will work only when the market is open, I should be able to update the code to work when the markets are closed so just leave it with me and I will get onto it as soon as I get some spare time.

That would be great Cja. It would be great to use this indicator at the weekends to prepare for Monday.

Thanks

Thanks again Cja, you never let anyone down and always with added bonuses.



15/12/15 Edit: Lines seem to be deleting automatically after a few minutes by themselves.
Also when changing timeframes the lines become selectable which make them prone to accidental movement or deletion.
Could you take a look please. The alarm feature is nice

16/12/15 - so far so good, lines not deleting, alarms working fine, lines are deselected on application, no timeframe change issues, only need to test at weekend when markets closed. Good work Cja, can't thank you enough.

Just downloaded and is brilliant however after marking up a few pairs gone back to them and the lines have disappeared, looked in Object list and nothing in there!

Any ideas please?
