What Happens When A Connection Is Lost

[dgregor5]

Hi:
I am concerned about the following scenario & would like to understand NT's thoughts on this.

1/ I am running a strategy via NinjaScript with an active trade in play with a trailing stop / profit targets orders in place at the exchange.
2/ Computer locks up & have to reboot.
3/ Re-open NT & have to re-activate the strategy - do I assume here that I have to include historical data in the strategy to resynchronise with the exchange).
4/ Strategy has to be active due to exit criteria (indicators) & trailing stop orders.
5/ Process steps for getting synchonised ???? ---- 1/ open NT, 2/ connect to e-signal (for historical data), 3/ activate strategy, 4/ connect to the broker.

Also in an alternative scenario where there is a temporary loss in connection (either directly to the internet or datafeed from the broker) & the systems automatically resynchronises ---- could this create any issues with order flow???

thx in advance
David

a) strategy is canceled as you disconnect
b) you are left with an active order/position in your account which is no different than just a regular strategy start with an active order/position in your account
c) temporary loss of connection will not make a difference for your live order/position. However strategy might have missed live bars and you might have to take action by custom code (supported by monitoring the connection status event in NT6.5) or manual action

thx.
But regarding point 'b'. yes i am left with an active order......however, with a trailing stop strategy or with an exit based on specific indicator criteria surely there would be need to be some way of resynchronising otherwise the only exit condition could be the 'old' trailing stop level or the profit target.

thx for your help

You would need to manually cancel the order and start again. There is no syncing to orders already in place.

Hi
I trade emini s&p on globex with datafeed zenfire. If I am in a trade with a stop loss and profit target (oco) in place and I loose connection will my orders be actioned if the relevant price is hit while I am offline
Also if in a trade can I log off happy in the knowledge my stop profit target if hit will be actioned
Thanks
Sam

Hi,

Just to quickly revive this thread here... I thought OnConnectionStatus gave us two parameters, one for "price" (Barchart?) and one for orders. Doesn't that mean we can monitor both connections?

Or is this a feature introduced in a later release than what was discussed previously?

>> Doesn't that mean we can monitor both connections?
Correct. The account connection has an internal order connection and an internal price connection (which might be different dependent on broker).
