To enable testing of different scenarios on the client side, we offer a range of ISINs, which are programmed to behave in a predefined way in our Sandbox environment.
For a comparison of the Live and Sandbox environments, view the Environments section.
The following lists give you an overview of these ISINs and their expected behaviour, including the order & execution webhooks.
The number of instruments in Sandbox and Live is different, and although some instrument IDs match, not all instruments do.
The ISINs listed here are designed to execute successfully in the Sandbox.
Please note that the for the ISINs listed here, the tax withholding is randomly assigned and may be 0.
To test the taxation, use the ISINs from the section Taxation simulations below.
The ISINs have the following behaviour and bid/offer prices:
| ISIN | Bid price | Offer price | Mock behaviour |
|---|---|---|---|
IE00BKBF6H24 | 7.51 | 6.23 | Successful execution |

IE00B5M1WJ87 | 100.00 | 100.00 | Successful execution with up to 5 partial executions. Number of executions dependent on order amount: < €101 = 1 execution, < €201 = 2 executions, ... > €401 = 5 executions |
All active ISINs in Sandbox not otherwise specified in this section (e.g., IE0032077012) | 100.00 | 100.00 | Successful execution |
To provide more realistic price simulations, we offer three (3) ISINs that use an updated approach for their price data in the sandbox environment. This feature algorithmically mimics normal market behavior to allow prices to increase and decrease over time. It also allows execution prices to more closely align the ISIN’s latest price as shown in the sandbox environment.
This functionality supports mocked behaviour on the following endpoints:
The mocked current price is exposed via:
GET /instruments/{instrument_id}/venues/{venue_id}/prices/latest.
The mocked price history is exposed via:
GET /instruments/{instrument_id}/venues/{venue_id}/prices/ohlc.
Access to these endpoints is available in the Sandbox environment for testing. To access additional price data (e.g., OHLC and latest prices) in Live, Clients must include the "Upvest Market Data Package" in their contract. Once enabled, clients will receive price data from our provider, Infront.
Please approach your Upvest account manager if you are interested in access to this price data in the Live environment.
We include enhanced dynamic pricing for the following three (3) ISINs:
- LU0429790743
- IE00B3VTMJ91
- IE00BF20LF40
Similar to real prices, these ISINs show smaller fluctuations in intraday prices. For example, within a ~20 minute interval, the price may change ~0.1 EUR as shown in the following chart.

For longer periods, the prices move in a way that reflects daily fluctuations with a general up or down price trend over time.

Success flow ISINs have the following expected order and execution webhooks:
ORDER.NEWORDER.PROCESSINGEXECUTION.FILLEDORDER.FILLEDEXECUTION.SETTLED
In the Upvest Sandbox environment, order executions are settled immediately, i.e. not on T+2.
The ISINs listed here are designed to mock different cancellation flows.
These ISINs have the following behaviour:
| ISIN | Mock behaviour |
|---|---|
IE00BYVJRQ85, LU0446734526, DE000A0F5UG3, E000YU9K6K2, LU1215452928, LU1834984798 | Upvest cancels an order immediately after PROCESSING state. |
LU1215451524, IE00BWT3KJ20, IE00BWT3KN65 | Upvest cancels an order in the PROCESSING state, however, not immediately. |
DE000A0H08H3, GB00BL9YR756 | Upvest cancels an execution; this is typically to be expected with mistrades. |
If you want to test limit and stop orders, you can use the following ISIN with prices oscillating every hour between 200.00 and 300.00.
Please note that for the ISINs listed here, the tax withholding is randomly assigned and may be 0.
To test the taxation, use the ISINs from the section Taxation simulations below.
| ISIN | Mock behaviour |
|---|---|
DE0005140008, IE00B9F5YL18, IE00B945VV12,IE00BK5BQX27 | Successful execution with prices moving sine-like every hour in the pattern: 250.00 (hh:00), 300.00 (hh:15), 250.00 (hh:30), 200.00 (hh:45) |
IE00B0M62Y33 | Behaves in the same way as DE0005140008, however, attempt to cancel the order in PROCESSING state will always get rejected. (Useful for ORDER_CANCELLATION webhook testing) |
Orders are being cancelled in the PROCESSING state:
ORDER.NEWORDER.PROCESSINGORDER.CANCELLED
Upvest will soon offer more transparency on cancellation reasons via webhooks. We will also document these changes in this section.
We provide some ISINs to test the tax withholding for sell orders.

| ISIN | Mock behaviour |
|---|---|
FR0000120644 | Gross: 0.04 with the following taxes: - Financial transaction tax (French): 0.04 |

Unlike the instant execution of ETFs, mutual funds are only executed once a day. You can test the delayed execution behaviour between ETFs and mutual funds by creating a portfolio allocation with any ETF instrument and one or both of the mutual funds listed here:
IE00B42W4L06- Vanguard Global Small-Cap Index Fund EUR AccIE00B18GC888- Vanguard Global Bond Index Fund EUR Hedged Acc

For the execution of portfolio orders, Upvest uses the block order functionality. To enable fast implementation and testing, we typically configure a block order execution every 15 minutes from Monday to Friday between 8am and 8pm. However, the execution time can be changed if you have other preferences.
Example
Assuming a portfolio order with a single ETF and a single mutual fund is placed at 8am on a trading day, the expected behaviour for orders and executions is as follows (learn more about the lifecycle of portfolio orders here):
- All individual orders (ETF and mutual fund) are created immediately (
ORDER.NEW) - The ETF is processed and executed at 8.15am (
ORDER.PROCESSINGfollowed byEXECUTION.FILLEDand immediateEXECUTION.SETTLED) - The mutual fund is processed and executed 18 minutes later at 8:33am (
ORDER.PROCESSINGfollowed byEXECUTION.FILLEDand immediateEXECUTION.SETTLED)
