Hi guys, I have a few beginner questions regarding the mechanics of stops, I'm on NT currently.

Stops - Is a stop triggered when there is a transaction at the stop order price? when a stop order price is reached, does the system then immediately take the ask price for a buy order and the bid price for a sell order?

Trailing and breakeven stops - In NT, we can set stop strategies using trailing and breakeven stops. I had experienced in market condition which is extremely volatile (sudden huge movements in split secs), a rising price triggered my trailing stop to move up but in the next sec the price had moved down against me resulting in the moving stop being higher than the actual price. As a result, NT will throw an error and the stop and profit target is removed. Is this normal? Does this mean I should not use trailing and breakeven stops in times with violent price movements?

Don't know if I have understood well, your position remain open and the your stop order and take profit are remove?
Anyway a stop order could be missed is some occasion, read here

Yes your understanding is correct. My position was a long, it remains open but the stop loss and profit target were gone after NT throws an error that the stop sell is above the current price.

I got a 2 ticks profit which triggered the trailing stop to move up then suddenly the price went down and below the trailing stop. Next thing I know NT threw an error and the stop and profit target is gone with my long position still open.

hi
I wanted to add a question to this; I am looking to set % profit & stops through the strategy builder (rather than coding) but not sure if it can be done. Here is the scenario;

say we enter long on the bar immediately after the trigger bar, 3 pips above the trigger bar. We want to place a stop immediately under the trigger bar, and also place a take profit 100% of the range of the trigger bar above the entry(or 200% or whatever). I notice there is a range indicator, which I presume can produce a variable for the range of the previous bar.

Just a question of whether I need to open code or can utilise the strategy builder.

Any help, muchly appreciated
