Groups of Streams
In addition to transmitting single data streams, InterChart Tools 1 includes “SendGroup” indicators which allow you to send similar data from either single or multiple charts. The multiple streams are processed (summed, min value, max value, or averaged) and displayed on another chart as a single data stream using the GetGroup indicator.

Volume Indicators
Volume data may be transmitted from a stock chart to an options or futures chart using the SendVolume and GetVolume indicators. The SendVolume indicator is different from the SendStream indicator because it accumulates data until the completion of a bar on the receiving chart.

Cautionary Note
There is no way to guarantee the order in which two separate intraday charts will update with a new bar, and thus it is likely that charts updating bars at the same time may not receive the most recent data. As an example, suppose a 1-minute chart is sending a stream to a 10-minute chart. Six times an hour these charts will update at the same time, and which updates first is usually a function of the unpredictable timing in which data is received, or other factors. Therefore at any one of those six times per hour, it is possible that the 10-minute chart will update and ask for streams a second or so before the 1-minute chart updates. The 10-minute chart will get the streams that are currently available, and will not wait for the 1-minute chart to update. Therefore it is possible that the 10-minute chart will receive 1-minute-old data from the 1-minute chart. Do not use these indicators where this could be a problem for you. Generally simultaneous updating is not as likely when at least one chart is a volume, tick, or range bar chart. To correct this problem, you can right click on the chart and select recalculate chart to manually update "out of sequence" operations.

Another time that older bars may be sent is when there are no bars to send. This could occur when there are gaps in price bars due to missing data, the exchange not being open, or other causes. When a new value for a bar is available, the bar may change. If you build a prediction or trading rules based on these bars, your signals could change.

Such problems may be less troublesome when sent data is received by the chart with the fastest bars.

InterChart Tools 1 will NOT work on charts that have more than one chartpage.

InterChart Tools 1 indicators include:

• SendStream – transmits a single data stream
• GetStream – receives a single data stream
• SendGroup1, 2, 3, 4, 5, and 6 – transmits up to 6 similar data streams
• GetGroup – accepts data from the SendGroup indicators and applies a treatment such as summing, extracting the minimum or maximum value, or averaging to compress the data into a single stream
• SendVolume – sends volume data. This indicator accumulates volume data until the completion of a bar on the receiving chart.
• GetVolume – receives volume data that accumulates since the last update

Examples

Example 1: This example shows how to send a 10 bar moving average computed on a 5-minute chart to a 7-minute chart.

The 5-minute chart contains the following indicator SendStream that uses a StreamID of 1: SendStream (1,Avg(Close,10))

The 7-minute chart contains the following GetStream indicator, which reads StreamID 1: GetStream(1)

Example 2: In this example a range bar chart computes the spread between an RSI on itself and an RSI from a daily chart.

The daily chart contains an RSI indicator that has been renamed DailyRSI. It also contains the following SendStream Indicator with a user selected StreamID of 13:

SendStream (13,DailyRSI)

The range bar chart contains an RSI that has been renamed RangeRSI. It also contains the following indicator:

Spread(RangeRSI,GetStream(13))

Example 3: The user in Example 2 also creates an hourly bar chart to which he would like to send the spread on his range bar chart. On the hourly chart the user wants to divide the spread by a moving average on one of his/her daily charts.

The following indicator is added to the range bar chart from Example 2, now called Example 3 Range SPY.cht:

SendStream (5,Spread(RangeRSI, GetStream (13)))

The following indicator is added to the daily chart from Example 2, now called Example 3 Daily SPY.cht:

SendStream (12,Avg(Close,10))

Then on the hourly bar chart called Example 3 Hourly SPY, the following indicator is added: Divide(GetSteam (5), GetStream (12))
