Yesterday's open, high, low and close

A very simple script to plot the yesterday's OHLC, to be used in an intraday graph.

There were other scripts like this, but their code was ugly, filthy, smelly, and WET, so I did this.

Versionshinweise: You can now choose to hide historical values.

Versionshinweise: Fixed the last bar bug that was displaying current day values. Very annoying.

Versionshinweise: Wrong graph ops

Versionshinweise: Ok now the graph should be right and working.

Versionshinweise: In Forex pairs, new data was being retrieved 1 candle before the closing of the day. Now it should be fixed.
