You can purchase the easy language code for all Intermarket indicators and strategies described in my book Intermarket Trading Strategies and 6 new ones by clicking on the Paypal icon below. These are not the original systems published in the book but were revised in 2019 to take into account correlation changes.
The package includes a Multicharts pla installation file or a Tradestation ELD file with 17 Intermarket indicators, 3 custom functions and 31 strategies and the manual (see list below). You can see how the Futures, Forex and Stock systems performed here and how the Gold systems performed here. The code is open (not password protected). If you already purchased the old systems sent me an email and I will refund you $99 (the price of the old systems).
