createFlag

Not working

createFlag accepts a flag, but Cloud9Trader never checks it, so onTrue and onFalse never run. Tracked in #228. Track the condition yourself instead.

declare function createFlag(config: { name?: string; condition: () => boolean; onTrue?: () => void; onFalse?: () => void }): void;

Instead

let wasAbove = false;

function onIntervalClose() {
  const isAbove = sma(20) > sma(50);
  if (isAbove && !wasAbove) {
    log("Fast average crossed above the slow one");
  }
  wasAbove = isAbove;
}
