Is there a way to set trailing stops based on the current bid and ask prices (or the midpoint of bid/ask, preferably) of a contract? In low-liquidity markets (like options), the bid/ask can increase without the "last trade" price increasing, so the stop doesn't move until an actual trade has gone through at a higher price.

We have found un-reliability among Trading services with Bid and Ask data at times. We do not use them to control Stops. We have found it to cause problems. However, there is a solution to this, what you need to do is use the -BAAVG suffix on the options symbol: https://www.sierrachart.com/index.php?l=doc/doc_RecordingModes.php This will cause the midpoint to be used.

That's a great feature. You guys really thought of everything. However, I'm running into a new problem - the historical data fills in just fine when I added the BAAVG suffix, however, it looks like the charts are not creating new bars. I see the bid/ask lines bouncing around, so the data may still be getting 'recorded,' but the last bar I see is the one that was current when I did a 'Delete All Data and Download" on all of the charts that I added the suffix to. |

Actually it looks like it's not being recorded. I had two instances where an entry signal was given, but it did not translate to an order. I think because the last piece of data on the chart where my entry study is running is from 30 minutes ago.

Are you using BAAVG on the main Symbol of the chart or on the Alternate Real-time Update Symbol?

I added -BAAVG to the Alternate Real-time Update Symbol - the options symbol. It gave me the historical B/A midpoint prices I want, but it did not update with new bars. Also something to note - I tried sending a manual order to IB just to see what would happen, and with the -BAAVG suffix, it rejected the order, saying it was an invalid symbol. Once I removed the -BAAVG, I could send an order. Should I be able to trade off a chart that uses the -BAAVG suffix? |

It is not going to work properly to set -BAAVG to the Alternate Real-time Update Symbol . It is not clear the reason you want to do that. What is the main chart Symbol set to? From our position, we do not have a good grasp of what you are doing. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Sorry - I got mixed up. The problem I was having with bars not updating was when I had the option symbol with the -BAAVG suffix on the main symbol. At that time, I wasn't using the Alternate Real-Time Update Symbol. Eventually I put the stock ticker in the main symbol and the option in the Alt Real Time Update Symbol as a work around to get things to update properly. But that was later in the day. That probably explains the order error I was seeing. So the main issue is probably just the chart not updating with the BAAVG suffix. Date Time Of Last Edit: 2013-05-03 23:48:13

I tried things again today, and definitely still no updating on any options charts with the -BAAVG suffix. I'm using the main Symbol (no Alt Real-Time Update Symbol used). If I remove the suffix, option charts appear to update OK. I've also tried a couple of other alternate recording mode suffixes (-BID, -ALL, etc) and the charts update with new bars, but almost all of the new bars are flat (i.e., the open/high/low/close values are all the same value, even though they shouldn't be). Here's a screenshot (currently set to -ALL, and note the position of the bid/ask lines): http://www.sierrachart.com/image.php?l=1367857981959.png It looks like, at least for options charts, the alt recording modes do not work properly. |

We will have to test this.
