Worried about strategy "bug"

[marcgrosso]

Hello, everyone

the problem is that some times it work and sometimes not, so I can't really understand why sometimes it works perfectly and sometimes not on same EVENT.

I'm connect to Coinbase with a SIM account

I've created an ATM using the option ninja trader provide me + deepseek R1(AI) to explain me everything

I'm posting some screenshot of what I did set up and I tryed on BNCUSD to trade

I do use BUYMKT or SELLMKT with the strategy.

The main issue is that I tryed everything spent more than 60hs doing this and the issue is that
50% of the time it work and reverse it even on big price change(drop or up) and some times it just complety ignore the change price, i'm not sure if its your ninjatrader desktop app that have issue or I'm doing something wrong.

anyone with some knowledge can point me toward the right direction?

The "EVENT" happened between 16.34 - 16.35

I found the problem it is actually a delay on DEMO acc + coinbase DB something like 250+ ms

Hello and respect,

I have reviewed your messages. If you notice this delay at a specific time, you should check whether that time coincides with high market volatility and increased trading volume.

If you always experience this delay, then yes, we can conclude that demo accounts have delays. However, if it only happens at certain times, this may not be the case.

Considering the +250 milliseconds delay you mentioned, it would be best to account for this in your ATM strategy to prevent potential losses.

Thank you.
