My very first custom indicator

Just created my first custom indicator. It is a buble indicator to track big orders using only level 1 data. Right now it is a very first version, so It will improve very soon

I don’t know how to access Best Bid and Best Ask of level 1 data with the level1

const quote = quotes.getQuote(); // Récupère la cotation actuelle (L1)

    if (quote) {

        bidPrice = quote.bid; // Meilleur prix acheteur
     askPrice = quote.ask; // Meilleur prix vendeur
    } does not work

const currentBid = dom.bid(); const currentAsk = dom.ask(); does not work
