Order Behavior

This page documents the behavior of TradersPost when receiving different types of strategy signals.
The details on this page are written under the context of buying and selling stocks. The behavior for other asset classes can vary depending on how your strategy is configured.
Buy
{
    "ticker": "TSLA",
    "action": "buy"
}
If there are open orders for TSLA, they will be canceled.
If a short position is open for TSLA, then the open position will be exited with a Buy To Cover order and TradersPost will wait for the exit order to fill.
If no long position is open for TSLA, then a Buy order will be sent.
If there is no exit order, no entry order and no orders to cancel then the signal will be rejected.
Sell
{
    "ticker": "TSLA",
    "action": "sell"
}
If there are open orders for TSLA, they will be canceled.
If a long position is open for TSLA, then the open position will be exited with a Sell order and TradersPost will wait for the exit order to fill.
If no short position is open for TSLA, then a Sell Short order will be sent.
If there is no exit order, no entry order and no orders to cancel then the signal will be rejected.
Price
If you send a value in the price field then a limit order will be sent unless configured to be a market order in the strategy subscription configuration.
{
    "ticker": "TSLA",
    "action": "buy",
    "price": 420.69
}
If you omit the price field in the JSON, then the resulting order will be limit order with the last quoted price if it exists or the ask for a buy and the bid for a sell.
Quantity
Sending a quantity with your signal will work for both entries and exits. The quantity will only be used if you check the Use signal quantity checkbox in your strategy subscription.
Use signal quantity checkbox.
Entries
For entries, if you send a signal quantity and enable Use signal quantity in your strategy subscription, then the quantity from the signal will be used for your entry order.
{
    "ticker": "TSLA",
    "action": "buy",
    "price": 600.00,
    "quantity": 5
}
If you omit the quantity field in the JSON, then the quantity will be dynamically calculated based on your strategy subscription configuration or if a quantity cannot be calculated, it will be defaulted to 1.
Exits
Sending a quantity with your signal for exits looks the same and has the following behavior.
If you send a quantity that is less than the total quantity of your open position, then a partial exit order will be submitted.
If you send a quantity that is greater than or equal to the total quantity available, or you omit the quantity, then the full position will be exited.
{
    "ticker": "TSLA",
    "action": "sell",
    "price": 700.00,
    "quantity": 5
}
Partial Exits
You can't specify a quantity using take profit or stop loss so instead you can partially exit a position like demonstrated on the example below. The first code block would be the entry, the second code block would be the partial exit.

Entry:
{
    "ticker": "TSLA",
    "action": "buy",
    "quantity": 5
}
Partial Exit:
{
    "ticker": "TSLA",
    "action": "sell",
    "quantity": 3
}
Sentiment
The JSON sentiment field in TradersPost allows you to specify what the sentiment of the position should be after executing the trade. When sending a webhook, you can include the sentiment field with a value of flat to exit a bullish or bearish position without entering the opposite position. This means that it will always exit the full quantity of the open position without entering a new position on the other side.
For example, if you send a JSON payload with action set to sell and sentiment set to flat, it will exit a bullish position without entering a bearish position. Similarly, if you send action as buy and sentiment as flat, it will exit a bearish position without entering a bullish position.
You are also able to have a sentiment of bullish or bearish. This is useful whenever you are partially exiting a position and you aren't fully exiting the position and you aren't changing sides. For example, if you are in a bearish short position with a quantity of 10 and you send a JSON payload with action set to buy, quantity set to 5 and sentiment set to bearish, this means that after executing the buy, you will still be in a bearish position with a quantity of 5.
Add to position
You can add to existing open positions by enabling the Allow add to position checkbox in your strategy subscription.
Allow add to position checkbox.
Normally, if you for example have an existing open long position and you send another buy signal, the trade would be rejected. However, if you enable Allow add to position, then the signal won't be rejected and an order will be created to add to your existing position.
Add Signal
Additionally, you can explicitly add to an existing position by using the add action. Here is an example where we add a quantity of 5 to the existing position. If no position is open then the trade will be rejected and no order will be sent to the broker.
{
    "ticker": "TSLA",
    "action": "add",
    "price": 700.00,
    "quantity": 5
}
Both Sides
When you receive a buy signal and you are trading both sides of a strategy, the following will happen:
If there are open orders for TSLA, they will be canceled.
If a short position is open for TSLA, then the open position will be exited with a Buy To Cover order and TradersPost will wait for the exit order to fill.
If no long position is open for TSLA, then a Buy order will be sent.
If there is no exit order, no entry order and no orders to cancel then the signal will be rejected.
The same is true for short positions. Here is what happens when you receive a sell signal:
If there are open orders for TSLA, they will be canceled.
If a long position is open for TSLA, then the open position will be exited with a Sell order and TradersPost will wait for the exit order to fill.
If no short position is open for TSLA, then a Sell to Open order will be sent.
If there is no exit order, no entry order and no orders to cancel then the signal will be rejected.
Exiting Without Swapping Sides
If you have both sides enabled in your strategy subscription and you want to exit the open position without entering a new position on the other side, then you can use the exit action.
{
    "ticker": "TSLA",
    "action": "exit",
    "price": 700.00
}
When trading both sides of a strategy, TradersPost requires that the exit be a market order. We will wait for 2 minutes for the market exit order to fill before submitting the entry order. If the exit order takes longer than 2 minutes to fill, the trade will fail and you will be notified via email and you will need to take manual action.
Manually Manage Both Sides
You can accomplish the both sides functionality by manually managing the entries and exits on both sides yourself instead of relying on the TradersPost both sides functionality. Keep in mind you are responsible for waiting long enough inbetween exits and entries, otherwise your entry could get rejected due to the exit order not being filled yet.
It is important that if you setup a strategy in this way, that there is time in-between the exit and entry signals. If you send both the exit and entry signal at the same exact time, you may experience unexpected behavior.
LONG
To open a long position, send a buy action to the webhook.
{
    "ticker": "TSLA",
    "action": "buy"
}
To exit a long position, send an exit action to the webhook.
{
    "ticker": "TSLA",
    "action": "exit"
}
SHORT
To open a short position, send a sell action to the webhook.
{
    "ticker": "TSLA",
    "action": "sell"
}
To exit a short position, send an exit action to the webhook.
{
    "ticker": "TSLA",
    "action": "exit"
}
Take Profit & Stop Loss
TradersPost has the ability to send take profit and stop loss orders with your initial entry order. This is useful for strategies where your entry, take profit and stop loss levels are all pre-defined and you want these orders to be sitting in your broker ahead of time.
If you are sending your take profit and stop loss to the broker with your entry order, it is recommended to not also have your strategy send duplicate exit signals to TradersPost when the take profit or stop loss level is hit in your strategy. Since the broker is executing your take profit & stop loss, there is no need to send a webhook to TradersPost to exit the position when the take profit or stop loss is hit in your strategy.
This functionality is only supported by brokers that support complex conditional order types that are often referred to as OTO (One Triggers Other), OSO (Order Sends Order), or OCO (One Cancels Other). It is currently supported by the following brokers within TradersPost.
Alpaca
TradeStation
TDAmeritrade
Tradier
How are take profit & stop loss orders calculated?
TradersPost supports the ability for you to send pre-calculated absolute prices for your take profit & stop loss or you can send relative values to us like a dollar amount or percentage and we will calculate the price to send to the broker.
For example, if you use a $10 stop loss amount and you enter at $100, then your stop loss stop price will be calculated at $90. If you buy 10 shares of a stock with an entry at $100 and a stop loss stop price at $90, then the most you can theoretically lose on the trade will be $100.
Or if you use a 5% stop loss and you enter at $100,  then your stop loss stop price will be calculated at $95.
When TradersPost calculates a take profit or stop loss price using a relative value like a dollar amount or percentage, the entry price we use to do the calculation will be the following in these scenarios:
If limit order, we will use the price from the webhook signal or the midpoint price from the latest quote if the webhook signal does not have a price.
If market order, we will always use the midpoint price from the latest quote.
You can configure your strategy subscription to include your take profit & stop loss settings, or you can send your take profit & stop losses with your webhook signal. Take a look at the Webhooks documentation learn more about how to send your take profit & stop losses with your webhook signal.
Min Move / Min Tick Size
Brokers often enforce what is a called a Min Move or Min Tick Size. This is a rule that controls how precise the price can be when sending orders to the broker. For example, the futures product M6E has a Min Move of 0.0001 (4 decimal places).
TradersPost will round prices to the nearest precision automatically for you so that the broker will not reject the order. For example, if you sent a sell signal with a price of 1.07375 and the Min Move is 0.0001 , then TradersPost will round the price up to 1.0738.
TradersPost will round up to the nearest precision for sell orders and down for buy orders. You can control the rounding on your side in your strategy and send a price with the exact precision to control the logic for rounding.
You can view what the Min Move value is in TradersPost by viewing the quote for the ticker you are trading.
This data can also be viewed in TradingView by clicking the three dots at the top of the chart and then clicking Symbol Info from the dropdown. Additionally, in TradingView PineScript, you can get what the Min Move is by using the syminfo.mintick variable.
Trade Retries
Added ability to retry trades that fail during trade planning. You can configure how many times to retry and how long to wait in between retries. This will only retry a trade if an API call fails when communicating with the broker during trade planning, it will not retry trades if the API fails after trade planning during execution. For example, if the broker API fails when we send an exit or entry order, we will not retry the trade. This is because we don't have a way currently to guarantee that the order creation did not actually succeed, even though we received a failure response back from the broker.
Isolate Sides
In the strategy subscription settings you can check the Isolate sides checkbox so that when paired with the Sides dropdown, you can limit a strategy subscription from touching a position on the opposite side of the Sides you have selected.
For example, if you have Sides set to Bullish and Isolate sides checked, the strategy subscription will not be allowed to close a Bearish short position if there was one open. Or if you have Sides set to Bearish and Isolate sides checked, the strategy subscription will not be allowed to close a Bullish position if there was one open.
Without the Isolate sides checkbox checked, if you have an open position on the other side of your Sides selection, TradersPost will first close the open position before entering on the other side. With Isolate sides checked, TradersPost will not be able to exit the open position and therefore will not be able to enter a new position on the other side and the trade will be rejected with a message as such.
