ToS/TradeStation chart discrepancies?

[uawgmsmco]

Does anyone else here use TradeStation for charting or even trading? I strictly trade futures with tick charts and the differences I'm seeing between the candlesticks are really quite bothersome. I suppose you could say to just "stick with one platform and don't worry about it", however I've been trading a successful strategy for years and there are certain parts of it that I'm attempting to automate with TradeStation. Compare the samples below.

Anyone else notice this issue? Was going to compare with TradingView charts but I'm not a subscriber so I can't access their tick charts. I'd love to say the differences are minuscule, but the theoretical P/L differences are huge between the two platforms.

I'm actually having this exact same issue Trade Station. Same with indicators providing different values including custom written ones that I know the logic is exactly the same. Quite frustrating when you can manually trade a strategy at every signal and then automate it in TradeStation with almost exact opposite results

I've noticed discrepancies between TradingView and ToS as well. I don't have an answer but I'm curious.

It would seem that this is a known issue. However, there is no total agreement as to why.

No mystery and not unknown. When it comes to time charts, there is agreement with when to start a one minute bar (as an example). Simply start aggregating new price data for a bar at the start of a minute and stop at the the end of the one minute period. If one platform were to start aggregating prices for a bar at 17 seconds into a minute and another did it 42 seconds in, each would show a different chart.

And while that would seem pretty silly with time bars because we know when we would like them to start, it's exactly what happens with tick bars as shown above. There is simply no standard for when to start counting -- no universal first tick. And so while both of those charts have a similar shape, they have very different looking individual bars. This is because they start at very different places.

With respect to the comment about TradingView differences, it's a different story. TV doesn't have TICK charts. However, for stocks, a free TV account only has access to data from trades executed on BATS which does not have the full, consolidated exchange data feed for all transactions. For liquid stocks they will look almost identical. For thinner stocks, especially on small timeframes TV charts can look sparse.
