What is correct configuration of input parameters for calculating RSI (and ROC)

I have tried to use Technical Indicators library to calculate RSI (and ROC) for candlestick’s closing prices, but when I compare results from Binance, I am not getting quite accurate results:

I fetch data using this Binance API:

This is example of usage for RSI and ROC indicators:

If I do this:

let inputData = {
        values: data, // 15 candlesticks, 1m candlestick data, values[0] is oldest closing price
        period: 14,
      };

and I do calculation:

const results_rsi = RSI.calculate(inputData);

I get single element array, with quite inaccurate result in compare to (realtime) data on Binance.

If I do this:

let inputData = {
        values: data, // 100 candlesticks, 1m candlestick data, values[0] is oldest closing price
        period: 14,
      };

 const results_rsi = RSI.calculate(inputData);

I get a result with a bunch of elements, and if I compare result_rsi‘s last element with Binance RSI 14 (1m) I get actually very accurate result. Also, I have read in one of the git issues that providing more historical data is better.

Now, so far so good… Or at least that is what I thought 🙂 However, both RSI and ROC results were very accurate.

The thing is, when I applied same logic, but with different parameters, say like this:

let inputData = {
        values: data, // 100(or even 200 and 500) candlesticks, 1h candlestick data, values[0] is oldest closing price
        period: 30,
      };

       const results_rsi = RSI.calculate(inputData);
      const results_roc = ROC.calculate(inputData);

and I check last element of results_rsi and results_roc (which I consider that are actual results, but maybe not?), I am still getting quite good results for RSI, but not for ROC I am getting very wrong results. It makes me think if I even use this library correctly, and I am not quite sure if even RSI results are correct, cause I didn’t try it for many different parameters.

So, the questions :

(from docs):

var data = 
[11045.27,11167.32,11008.61,11151.83,10926.77,10868.12,10520.32,10380.43,10785.14,10748.26,10896.91,10782.95,10620.16,10625.83,10510.95,10444.37,10068.01,10193.39,10066.57,10043.75];

var period = 12;
        
var expectResult = [-3.85,-4.85,-4.52,-6.34,-7.86,-6.21,-4.31,-3.24];
    
ROC.calculate({period : period, values : data});

What is the actual result of ROC here? Cause the array is returned.
How input values should be sorted? (what should be the values[0])?
Where am I wrong? 😀
