In Tradestation the Renko inputs are in points - Not ticks. So if you were putting in “1” in Tradestation - it would actually be 4 ticks on the @ES for example.
Tradovate has their inputs as ticks.
If you were entering 4 in Tradestation then it was a 4 point Renko. If you use 16 on Tradovate (Assuming it is the @ES) it should match.
Hope that helps.
