Open range code for currencies

Hello, what has to be changed in this code so that it shows low / high and differential values for currencies.
Many thanks for your help

// Opening Range EUR with Close and Open.
// Added some changes and features.
// - segment for opening price;
// - segment for yesterday's closing price;
// - Automatic detection of the timeframe;
// - Automatic configuration for 1-5-10-15-30min charts.
