Retroactively update bar indicator values.
AnsweredSome indicators, such as the Williams Fractal, require the ability to "look ahead" into the future to generate a signal. For example, if the candle 2 periods from now closes higher than the current bar, the current bar should have a buy signal.
We require the ability to do access bars in the past and update their properties. (And if this *is* possible today, we need guidance in how to do it.)

Indicators like TTM Scalp (referenced here https://tradovate.zendesk.com/hc/en-us/community/posts/360037616853-TTM-trend-and-TTM-scalp) also require the ability to update past bars with a buy/sell signal. For example, if the prior two bars close under the low of the highest bar, add an arrow signal to the highest bar.

Hi Dave,
Thanks for the request!
As a little color for this response...we're currently in the middle of a rather large project to update our chart internals. This is the first step in allowing us more flexibility with indicators as well provide a foundation for us to move into strategies and backtesting.
As a side effect of our work on the charting internals (as well as using WebAssembly) we will begin support of indicators written in other languages (like C++). C++ provides a complete history and an indicator can change past signals if built using C++.
So, short answer: this will be available soon, but will require the indicator to be written in C++
