For example, Bar Magnifier is helpful when both the profit target and stop loss occurred on the same bar. In this situation, it is unclear whether the profit target or the stop loss occurred first. With Bar Magnifier, MultiCharts is able to see how the bar was formed to determine whether the profit target or the stop loss occurred first.
<div style="background-color: #E3FBE5;">Note: We suggest to use tick data because it is most precise.</div>
<br>To use the feature:
## Open the '''Format Objects''' window.<br><span>{{FormatObjectIS}}</span>
## Select the '''Signals''' tab.
## Click '''Properties''' button to open the '''Strategy Properties''' window.# Select the '''Signals''' tab.# Click '''Properties''' button to open the Strategy Properties window.
# Select the '''Backtesting''' tab.
# In the '''Backtesting Precision''' section, select the '''Use Bar Magnifier''' checkbox.<br># MultiCharts will break down each bar into a series of lower resolution bars so that it can look to see how the bar was formed.:
#* Select the '''Tick''' radio button if the chart has tick-based resolution. Enter the number of ticks for the lower resolution bars. The number of ticks must be at a lower resolution than the chart resolution, or
#* Select the '''Intra-day''' radio button if the chart has minute resolution or daily resolution. Enter the number of minutes for the lower resolution bars. The number of minutes must be at a lower resolution than the resolution of the chart, or
#* Select the '''Daily''' radio button if the chart has weekly resolution or higher. MultiCharts will break down each bar into daily bars to see how the bar was formed.
# Select Check the '''Skip ticks with identical prices''' checkbox for faster backtesting. MultiCharts will skip ticks with identical prices when it constructs the lower resolution bars.# Check the '''Enable access to intra-bar time for calculation in Intra-Bar Order Generation mode''' checkbox to make intra-bar time (timestamps of the detailed data series selected in Bar Magnifier) available from PowerLanguage script ([[Date]], [[Time]] and [[Time_s]] keywords).
