Example

// Get the open price of the current bar for EURUSD on H1 timeframe
const currentOpen = this.api.iOpen("EURUSD", 60, 0);

// Get the open price from 5 bars ago
const pastOpen = this.api.iOpen("EURUSD", 60, 5);

// Calculate the difference between current and previous bar's open prices
const openDiff =
  this.api.iOpen("EURUSD", 60, 0) - this.api.iOpen("EURUSD", 60, 1);

// Check if current bar opened higher than previous bar
if (this.api.iOpen("EURUSD", 60, 0) > this.api.iOpen("EURUSD", 60, 1)) {
  console.log("Current bar opened higher");
