Bar Close and Loops

[snaphook]

Will a Bar Close cause a break out of a loop such as a for or while loop?

No. When you are in a loop you are processing only one tick. Subsequent ticks are not processed yet.

What I am trying to do is write a stop and reverse routine for an autotrader. If conditions are right I issue a close command to close the current position.

AtmStrategyClose(atmStrategyId);

Then I want to wait for it to flatten all positions. So I put it into a while loop continually monitoring the MarketPosition.

while(GetAtmStrategyMarketPosition(atmStrategyId) != MarketPosition.Flat && n<1000)
{
++n;
}

The n<1000 and ++n are simply to exit the loop during testing on sim 101 or tick replay. I have not traded this against a broker's sim account so it never goes flat in time to enter a new order because CalculateOnBarClose = True.

Will this work? Without the n exits, it just loops forever and requires a rude interrupt because sim101 never gets a new tick to process the closposition command.

Most likely not. You need to receive the next OnBarUpdate() to receive new MarketPosition updates. With that loop you are halting it from processing further information down the queue.

Thanks. Back to the drawing board.
