Looking for help turning some code into currency indexes on Trading View

Hi, I have the calculated  weighting formula Code for all the major currencies index charts, the index measures the strength of a currency by directly calculating it against several other currencies using a weighting. For example, the DXY, or USD currency index has the EUR as its major weighting, it generally makes up 224.6 % of the overall comparison, the EURJPY, for example, makes up 0.0189% of the equation. However you don't have to worry about doing any of the weighting calculations, I already have all of those for the major currencies, AUD USD EUR CHF JPY NZD CAD GBP, I will supply you with that information. Your task is as follows, simply take the code given and work out how to copy and paste it into Trading View (top left-hand box), and bring up these index charts so they can be used in any time frame with any indicator. I need to know how the data feed works, is it tick data, M1? the data cannot be lagging behind the pair chart. I have included some screenshots, first is how the old LiteForex indexes used to look and second is how I use indexes and charts in tandem to formulate trades on Trading view. Problem id on Trading View the data lags especially on the USD.

TIA 👍
