ATM - Help with trailing auto stop

[NinjaTrader_Tyler]

Hello backtester831,

Thank you for writing in today.
I have attached a screenshot showing the parameters for your desired stop strategy:
First, we have the strategy set to move the stop loss to 8 ticks above break even after 16 ticks of profit.
At 24 ticks of profit, the stop loss moves to 8, which is equivalent to 16 ticks above break even. The frequency is set to 8, so the stop will trail the market every 8 ticks.
Below I have provided a helpful link for Stop Strategies in NinjaTrader 8:

Please let us know if we may be of further assistance.

Having trouble setting this up, hoping to get guidance on this.

#1. After 16 ticks of profit, set stop to 8 ticks of profit.
#2. After the above, then have a trailing stop moving the stop up 8 ticks after every additional 8 ticks of profit. So at 24 ticks, the stop goes to 16 ticks, etc.

In the screenshot, the auto breakeven setting takes care of #1, but not sure how to setup #2. I've tried setting the auto stop loss and profit triggers to 8, but then that overrides #1. Only want the auto trail to start after #1.
