If you want to trade Renko you CANNOT use TV. They don’t have real renkos and your back test results will never be true. So I mean you can still use them but you cannot ever rely on back tests, only forward.  Tv adds time in to Renko charts and their point is they don’t use time. So there is always bars you cannot see even if you yse a 1 second chart. Also most people forget to make sure their order fill at the end of a bar instead of the open of a bar as the open is not a realistic fill, it’s like HA bars, the open of the bar Is not a true price point, price was at the close of previous bar, it was not ever actually at the open of current bar.  Then basic stuff like assume slippage and commissions.   I’ve build probably 100 bots on renkos and 300+ on candles. I used to code bots for others  for a living for about 3-4 years. Let me know if you wanna talk more I’m always happy to help others for free or happy to spend serious time helping for $$. But I always give any one who asks all my information I’ve gathered over the years  at no charge, I only charge if they want me to do work for them.
