A sample indicator, test_rsionarray.mq5, demonstrates the application of the Crsionarray class. The incrsionarray file should be placed in the MQL5\Include\Inconarray directory of your terminal data folder (the Inconarray folder must be created).
The Cmaonarray class from the incmaonarray file is required for proper operation.
The RSI is a price-following oscillator that ranges between 0 and 100. A common technique for analyzing the RSI involves identifying divergences, where a security reaches a new high, but the RSI fails to surpass its previous high. This divergence suggests a potential reversal. When the RSI turns downward and falls below its most recent trough, it has completed a "failure swing." The failure swing is considered confirmation of an impending reversal.
