Got tired of seeing people paying good money for these trading/investing tools so I built a website and added the tools so people could use them free. I have several trader tools. It’s more of a financial website to help investors and traders. There’s a pit board for sizing risk and journaling trades, plus a volatility calculator and a gap-fill calculator. It still needs some work. https://reddit.com/link/1whlr39/video/mzntc1fmwsph1/player submitted by /u/Sudden-Journalist-60

摘要：发帖人因看到人们花高价买交易/投资工具，做了一个免费网站，提供仓位风控与交易日志板、波动率计算器、缺口回补计算器。帖子只说明仍待完善，未给出收入或用户付费数据，但间接验证了交易工具付费市场存在。
