How to use Momentum(20)[0] to identify and entry

[williamzz]

Hi,
Dear team!
I'm new to NinjaTrader. I'm testing a strategy.But my strategy can't identify the big momentum time.

I do notice that there is a Momentum(20)[0] function.

Can you give me an example of how to use it to identify the momentum,or how to use
Slope(EMA(20), 5, 0) to identify it? Thank you so much!!

Hello williamzz,

Thanks for your post and welcome to the NinjaTrader forums.

From the help guide, the definition of the momentum indicator is: "By measuring the amount that a security's price has changed over a given time span, the Momentum indicator provides an indication of a market's velocity and to some degree, a measure of the extent to which a trend still holds true. It can also be helpful in spotting likely reversal points." https://ninjatrader.com/support/help.../?momentum.htm I recommend that you add the indicator to a chart of the instruments of interest and visually review the movement of the indicator compare to the price movement and determine for yourself what an entry condition would be. You can also vary the "period" that the indicator is calculated over to gain a different time perspective. You can also use multiple Momentum instances each with a different period and from this again you might see what looks good to you for an entry.

From the help guide, the definition of Slope is: "Returns a measurement of the steepness of a price series (y value) measured by the change over time (x value). The return value can also be thought of as the ratio between the startBarsAgo and endBarsAgo parameters passed to the method." https://ninjatrader.com/support/help...-us/?slope.htm You can apply most any input to Slope and in your example, you are obtaining the slope of a 20 period EMA of a 5 bar range. I recommend printing out the values of slope on each bar so that again you can review what values relate to the steepness on interest (the help guide example shows a print statement). Please note that this will be different from one instrument to the next because the price references are different. The Slope allows you to specify both a start and end bar for the slope determination so again you may want to plug in different values or again you may ultimately want to use more than one slope measurement to see the change of interest.
