...sceeto puts a time stamp on our data up on the ...sceeto cloud.  The ...sceeto client then works with your NinjaTrader application to marry the data to the correct time\place on your price chart.

Neither application has a preference for when\where you marry the data with price - so feel free to use a 20 second chart.

We frame our work with a 4 tick range bar chart for ES as this is the chart setting that we use on the ...sceeto cloud, and also because it offers very good tick level insight into when order flow can have an affect on price.
