yoni / set_asking_prices.js

Last active January 1, 2016 08:19

On Lending Club, the aftermarket (i.e. FolioFn) trading form entry is pretty horrible. This little script allows you to set a discount amount (e.g. 90%) and apply it to all loans' asking prices.

	var discount = 0.9; // set this to your own discount policy
	var outstanding = document.getElementsByClassName('outstanding-principal-accrued-interest');
	var askingPrices = document.getElementsByClassName('asking-price');
	Array.prototype.slice.call(outstanding).forEach(
	function(entry, i) {
	var outstandingAmount = entry.textContent.replace(/[$]/g, "");
	var askingPrice = (outstandingAmount * discount).toFixed(2);
	askingPrices[i].value = askingPrice;
	}
	);
