A not so known option in MT4

One of the big issue you may have with MT4 is that when you look at the chart in bar or candle mode, MT4 uses the high/low value showing on the present chart to adjust it's size.

The inherent problem is that in calm market, the chart kinda zoom in naturally and shows zoomed in indicator as well.

A simple could seem to have a good slope when in fact it is more or less flat.

To circumvent this you can use the following option, go in the properties of your chart (default F8 ) and tick "Scale fix" one to one and "Scale fix"

see attached screenshot.

Only issue with this is that when you scroll your chart with the mousewheel, the chart scroll left/right but not up/down so you can eventually lose the price line.

This option is particularly usefull for Bollinger Band like indicators.

I find it easier just using the scale fix, I watch 9 pairs and have them all set on a 300 pip scale on a 1 hour chart, that way you start to get a feel for how big / small moves are, and you can see which pairs are making the largest moves.

Only trouble is if you apply a new template you have to go through the charts again and rest the scale.

an even lesser known trick if you lose the price when scrolling in scale-fix mode is to hit the 5 key on your keypad to center the price.
Woot!
