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.

Note di rilascio: Now you can select which timeframe do you want to pull the data from, so you choose to plot the last week OHLC, or the last month.

Note di rilascio: The script is now useful on daily and weekly charts, and you can set the period so that lines are shown on the chart.

Note di rilascio: I changed the default style of the lines to be the regular lines instead of the step lines, so now, if you have selected the display current values options, the lines should be visible even at the start of the day.
