Here is an update to the inside bar indicator. In addition to the arrows indicating which bars are inside bars, it draws a box around it including the user set buffer, and text below the box tells you the size in pips of both the inside bar and buffer zone.
You can also tell it to use push alerts, to send notifications to your smart phone via the mobile MetaTrader 4 app.
This particular indicator calculates inside bars as the high and low being "inside" the high and low of the previous candle.
The colours and text locations are not user adjustable, but if there's interest, I can modify it to include these features.
