It is designed to signal an  alert condition only once per bar when  update every tick is turned on.&nbsp;</font></p> <p class="MsoNormal"><font face="Arial">Without this enhancement, will alert you on each tick of a bar which meets your alert condition. For example, a 15-min bar in the ES market has about 150 ticks per bar. Thus, depending on the number of times your condition is met during these 150 ticks, you will get an  Alert message box popping up each time.&nbsp; You could actually get up to 150  Alert boxes popping up during each bar! This can be extremely annoying and distracting while trading.&nbsp;</font></p> <p class="MsoNormal"><font face="Arial">But with the  Alert Once enhancement, you ll only get the first  Alert box and all others for the current bar will be suppressed---even with  Update Every Tick turned on.&nbsp;</font></p> <p class="MsoNormal"><font face="Arial">With the  Alert Once enhancement, you can replace or enhance the TS built-in  Alert function. Here are some ideas:</font></p> <ul style="margin-top: 0in; margin-bottom: 0in" type="disc"> <li class="MsoNormal">Alert only once per bar when a condition is met.</li> <li class="MsoNormal">Alert only once per condition and not again until another condition is met.</li> <li class="MsoNormal">Alert when condition 1 is met and then alert again on the same bar when condition 2 is met.</li> <li class="MsoNormal">Alert only once per bar and play a sound file when a condition is met.</li> <li class="MsoNormal">Alert once and never alert again.</li> </ul> <p class="MsoNormal"><font face="Arial">&nbsp;The  Alert Once enhancement&nbsp; is fully compatible with TradeStation 8 and can be used on multiple charts using multiple indicators. </font> </p> <hr size="1"> <span style="font-size: 12pt; letter-spacing: -0.1pt"> <font face="Arial" size="2">Neither TradeStation Technologies nor any of its affiliates has reviewed, certified, endorsed, approved, disapproved or recommended, and neither does or will review, certify, endorse, approve, disapprove or recommend, any trading software tool that is designed to be compatible with the TradeStation Open Platform.</font></span><p> <font size="2" face="Arial"><i><strong>Copyright © 2003 Investment Engineering Corporation.
