The range and the shading

The open session's range

While a session is open, Tempo shows its high and low so far — not the day's, that session's.

The gauge, which is what saves the work

Next to the range sits a small bar with a marker. The marker says where price is right now inside that range: hard left at the low, hard right at the high, in the middle in the middle.

It looks like a small thing and it is not. The alternative is reading three six-digit numbers — high, low and price — and doing the subtraction in your head every time you glance up. The gauge gives you the answer before you have read a single number.

If the range is flat — a session that has not moved yet — the marker sits in the centre rather than at some arbitrary end.

The shading over the candles

As well as the bar at the top, Tempo tints the chart background with the colour of the session each candle belongs to. That way the bar above and the price below tell the same story, and you do not have to look up and down to work out which session something happened in.

Strength is set with InpSombraPct, from 5 to 60 %. The default is 22 %, which reads without covering the candles.

Something you may notice: the shading does not weigh the same across palettes, even at the same percentage. Heavily saturated colours — Tokio Night's neons, Bloomberg's amber — read stronger than muted ones at identical transparency. Tempo compensates for that, so Bloomberg at 22 % and Oscuro Pro at 22 % land in much the same place on screen. If you set a very vivid colour of your own, it gets the same compensation.

Turn it off with InpVerSombreado.

Why the shading seems to stop before the edge

Look at the right-hand edge of the chart and you will see an unshaded strip. That is not a bug: it is the margin MetaTrader leaves to the right of the last candle. There are no candles there to shade.

You remove it in the terminal itself (right-click > Properties > Show > Chart shift), and then the shading runs all the way.
