Price often reacts at certain key levels, like a Yesterday High/Low or Last Week High/Low. If you're in an open position and you reach one of these levels, often you want to be able to take a look at the chart and see if you want to get out of the position, even if it's not at target yet. You might do this if you're in a lot of trades and the risk load is really high, and you would rather take a smaller gain than have price react strongly against you and take all that risk into drawdown.
This is a strategy file for Chart Logic that monitors Key Levels, and will send you an alert any time you're above/below the key level for a symbol where you have an open position. The alerts have a 1-hour delay.
