Support & Resistance Line Width

Hi,

Can someone experienced in trading tell me usually the width of the support and resistance lines should be?

I trade the 15 min majors. Personally, I feel 1-2cm width on the screen is enough? I have seen others use 5-10cm between S&R lines I imagine this is for swing and position traders.

Thanks.

Think of them as zones.

When drawing support and resistance, it's better to use a crayon instead of a pencil...........

It's up to you

There's no practical difference between drawing a support line and a support "zone" (wider). It's all in your head. If you are drawing a thin line, it starts at a specific point and ends there, however all it is doing is indicating that you are approaching potential support/resistance-- how far beyond (if at all) price may breach into the zone (before reversal, assuming it holds) can not be known, therefore the width you draw of the support line is materially irrelevant.

My prefered way is to draw them as you see them. You'll soon see the zones and they will be the width that the market has made them.

Try this.

Could someone tell me when a support of resistance line fails and is to be deleted from your chart?

Very much depends on the time frame. Just because a S/R line is broken on a daily chart doesn't mean it won't be respected later. On the hand an S/R line on a 5 minute chart may be insignificant one hour later.

Look at higher time frames, say 4H and above. Zoom out and notice where price has reacted or turned. These are likely to be significant lines and may be valid for long periods of time.

Watching price action at these lines is crucial to many trading techniques but that is another story.
