// Version 2.0 of my previous renko strategy using Renko calculations, this time without Tilson T3 and without using security with Renko to remove repaints!
// Seems to work nicely on cryptocurrencies on higher time frames.

//== Description ==
// Strategy gets Renko values and uses renko close and open to trigger signals.
// Base on these results the strategy triggers a long and short orders, where green is uptrending and red is downtrending.
// This Renko version is based on ATR, you can Set ATR (in settings) to adjust it.

// == Notes ==
// Supports alerts.
// Supports backtesting time ranges.
// Shorts are disabled by default (can be enabled in settings).
// Link to previous Renko strategy V1: https://www.tradingview.com/script/KeWBWLGT-Renko-Strategy-T3-V1/
//
// Stay tuned for version V3 in the future as i have an in progress prototype, Follow to get updated: https://www.tradingview.com/u/dman103/#published-scripts
