Buy at Close

[Lalocom]

Yes I know there is no such an order. I'm trying to find the best way to acomplish this without loosing any opportunity, nor tick.

My system:

- 2 instruments
- primary instrument 150 tick bars
- secondary instrument 1 minute bars
- signals are fired from the primary instrument
- I want to buy on secondary instrument on the first price of the bar, at open.

Solutions:
- Use OnBarClose = true; in the Intialize() method -> This sentence only regards primary instrument!
- Use BarTimer or system time to fire a market order -> That will be great, but my system clock is quite inaccurate
- Use FirstTickofBar -> Sorry too late, remenber I want to be the first

I would really appreciate any idea that helps me to achieve my goal.

Thanks
Lalocom

Lalocom, it would seem then a logical solution to sync the PC clock with tools like Dimension4 / Atomic Clock Sync at regular intervals throughout the trading day and submit an order for example 1-2 seconds before the prior BIP1 bar finishes -> that would be very close then to the 'unknown' next bar open.

Dimension4 / Atomic Clock Sync.

It looks great.

Thank you Bertrand. I'm gonna try.
