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.

Note di rilascio: You can now choose to hide historical values.

Note di rilascio: Fixed the last bar bug that was displaying current day values. Very annoying.

Note di rilascio: Wrong graph ops

Note di rilascio: Ok now the graph should be right and working.

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