Need help about SRSI

[shamanaia]

Hi @sindelio, coding is my hobby and async arrow functions is new for me, I could't find any ansewer on MDN, even SOF :), so please can you excplain me line 95-111 in bot_public.js

I use it without yarn.

// Initializes the Ehlers filter (super smoother)
const initializeSmoother = async (SRSI) => {
	console.log('INITIALIZING SUPER SMOOTHER');
	filter[0] = c1 * (SRSI[1].stochRSI + SRSI[0].stochRSI);
	filter[1] = c1 * (SRSI[2].stochRSI + SRSI[1].stochRSI) + c2 * filter[0];
	filter[2] = c1 * (SRSI[3].stochRSI + SRSI[2].stochRSI) + c2 * filter[1] + c3 * filter[0];
	console.log('smoothedStochRSI: ', filter[2], '\n');
}

// Calculates next value for the Ehlers filter
const calculateSmoother = async (SRSI) => {
	console.log('CALCULATING SUPER SMOOTHER');
	let newValue = c1 * (SRSI[3].stochRSI + SRSI[2].stochRSI) + c2 * filter[2] + c3 * filter[1];
	filter.push(newValue);
	filter.shift();
	console.log('smoothedStochRSI: ', filter, '\n');
}

(SRSI) and SRSI[*].stochRSI

they are variables, function names or refference to some external node modules like line 90?

StochasticRSI.calculate(inputStochRSI)`

or something else. I can't realise there origin and nature.

As can see in console it's array:

Thanks in advance.

Thanks for reply.
so, as I understand here ".stochRSI" is reference to "/node_modules/technicalindicators" and "SRSI" is parameter of async, but if SRSI is NOT declared yet, how it can own array ellement? SRSI[1]?
I will be grateful for your answer.

Thanks.

I recommend you use chatGPT to ask these questions, it will probably answer better than me xD Also, you need to study JavaScript fundamentally. There is a book called "You don't know JS", If you wanna really get good with it. Best of luck!
