AmountToLotSize works incorrect

[ramilexe]

There is MEWUSDT token on Binance futures with following parameters:

"pricePrecision": 7,
"filters": [
{
    "filterType": "PRICE_FILTER",
    "minPrice": "0.0000010",
    "tickSize": "0.0000010",
    "maxPrice": "200"
}]

When I call AmountToLotSize(0.0000010, 7, 0.003923153000000002) I get 0.0039229 but expected value is 0.003923. Because of that I get error <APIError> code=-4014, msg=Price not increased by tick size.

thanks for your feedback, it is no longer applicable at present, I saw. @ramilexe I recommend that you follow tickSize completely, not pricePrecision. I would fix this function later.

{
			"filterType": "PRICE_FILTER",
			"maxPrice": "200",
			"minPrice": "0.0000010",
			"tickSize": "0.0000010"
		}

@xyq-c-cpp I replaced it with following function:

// RoundPriceToTickSize rounds the price to the nearest tick size
func RoundPriceToTickSize(price, tickSize float64) float64 {
	if tickSize == 0 {
		return price // To avoid division by zero
	}
	// Calculate the factor by which to multiply and divide the price to conform to the tick size.
	factor := 1 / tickSize

	// Round the price to the nearest tick size.
	roundedPrice := math.Round(price*factor) / factor

	return roundedPrice
}

@xyq-c-cpp @adshao in which PR it was fixed?
