Struggles when using my Strategy at different Futures / at rollover

[debleded]

Hello everybody,

i built a strategy with a scalping approach, what i used at Backtesting and in realtime (Simulation account),
Instrument was the ES 03-21.
The strategy behaved as it should (tested years back in strategy analyzer, with tick replay and secondary 1 - Tick data source)
I got similar results in realtime (simulation account).
Screenshots are attached.

Now i tried the strategy at the latest ES 06-21 contract, where the strategy obviously doesn´t work. It seems like all entry and exit conditions got disregarded.
Same results and FDAX 03-21 and FDXM 03-21.
Screenshots also attached.

Does anybody know a solution for my problem?
(I suscribed the market data for ES and FDAX, FDXM and in the chart i see the data working/changing)


Thanks in advance for your help!

Got the mistake now,

secondary data series was ES 03-21, changed it on primary data series.
Now it works as intended.
