MT4 Trendline Drawing Technical Help

Hi - My trading strategy involves drawing trend lines precisely in MT4, these often need to run through the very tip of a high or low of a candle bar and it can be tricky to zoom right in and get it exactly perfect. Slight variations have a big effect on a long 'ray' TL. I have two questions for all the MT4 experts to see if this could be made easier.
1 - Is there a way to 'lock/anchor' the TL to the high or low tip of a candle that it touches? Either existing in the program or as an add on.
2 - Does anyone know how to make the little 'handle' boxes on the TL (used to adjust it) transparent? Mine are white and it makes it hard to see the high or low that I am trying to position it on. These boxes were transparent with another broker's version of MT4 so I know it is possible but I have tried editing the colour-scheme etc in this version of MT4 and I can't seem to find it anywhere.

Thanks in advance for any assistance.

Yes there is,

1. Go to Tools, Options, in the Objects Tab increase magnet sensitivity in the drop down box.

2. The trendline colour can be changed within the trendline drawing tool, but you can have the "little handle boxes" visible each time you create an object
by ticking the Select object after creation box.

3. By tcicking the box above "Show Properties after creation" you can change colour & line thickness or even name the trendline, when the dialogue box appears.

That works perfectly, cheers fella
