This is a Increase icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
This concerns investing money. When stocks are on the rise it is called bullish. The symbol is an arrow on top of a series of lines in a row standing upward and progressing higher and higher. The arrow follows the highness of the lines.
