Yesterday ( 2015 01 15 ) this indicator could save many accounts which traded CHF pairs and not only after the 2800 pips drop of EURCHF (in some brokers I measured that the drop was 7800 pips and the spread the same time was more than 300 pips).
Thanks to God this drop did not harm me at all.
I believe that Spread Level Pro is a must for every Strategy.
It can save your entire account from crashes like this and not only.

Consequently, it should be put into the strategy properties rather than to use an indicator slot.

Fixed visualization of the spread on Builder mode. However, you should not use this indicator for backtesting since the history data doesn't contain spread information. The indicator shows a fixed value on Builder mode.

Indicator updated. Fixed wrong representation of pips and points. The indicator must be set in points.

If you have file names issue, delete the indicator from both "Indicators" and "Libraries" folders.
