Take a security, whose you plot the latest 100 bars. Then you plot a 20 days moving average and a 14 days RSI. Well, it would be interesting to add a "show plotting since" function, in order to show on the chart just a fraction of various indicatos chosen. Sometimes plotting different MAs and indicators could add some troubles and confusion; so it would be great to show 14-d RSI and 25-d MA for the latest 50 bars only, if requested by the user.
