The source chart chosen by traders is important no matter what the Renko 
chart generator is. Both charts in this folder were produced by the
STG Renko Chart indicator. At first glance you might say that they are
similar since, for June 3, the 4 arrow signals and the number of Renko 
bricks are the same although the last brick from the M5 source chart wasn't
completed when trading ended for the day.

If you look at the number of volume bars you will see, if you magnify the
charts, that there are 41 bars on the Renko chart produced by the source
M1 chart and 14 on the Renko chart produced by the source M5 chart. 
Although not important, you will notice that the time indicated on the 
bottom of both charts are different.

Excluding the first and last Renko brick of the day, you will see that the
number of Renko bricks was 49 on June 3. Since there were 41 volume bars on
the Renko chart produced by the M1 source chart 8 of them are missing
while 35 are missing on the Renko chart produced by the M5 source chart.

Since the charts look similar you might think that this isn't important
but this isn't the case. This is because when there is a gap on the source
chart due to missing volume data a Renko EA/indicator fills the gap with
Renko bricks with no volume until it finds one with volume. This confuses
traders, including me, when we see many Renko bricks seemingly appearing
from nowhere. To avoid this problem as much as possible please always a
M1 source file although you could choose another timeframe and the Renko
chart would look exactly the same.
