// This experimental Indicator helps identifying instituational Order Blocks. 
// Often these blocks signal the beginning of a strong move, but there is a significant probability that these price levels will be revisited at a later point in time again. 
// Therefore these are interesting levels to place limit orders (Buy Orders for Bullish OB / Sell Orders for Bearish OB). 
//
// A Bullish Order block is defined as the last down candle before a sequence of up candles. (Relevant price range "Open" to "Low" is marked)  / Optionally full range "High" to "Low"
// A Bearish Order Block is defined as the last up candle before a sequence of down candles. (Relevant price range "Open" to "High" is marked) / Optionally full range "High" to "Low"
//
// In the settings the number of required sequential candles can be adjusted. 
// Furthermore a %-threshold can be entered. It defines which %-change the sequential move needs to achieve in order to identify a relevant Order Block. 
// Channels for the last Bullish/Bearish Block can be shown/hidden.
//
// In addition to the upper/lower limits of each Order Block, also the equlibrium (average value) is marked as this is an interesting area for price interaction.
//
// Alerts added: Alerts fire when an Order Block is detected. The delay is based on the "Relevant Periods" input. Means with the default setting "5" the alert will trigger after the 
// number of consecutive candles is reached.
