Hi,
Is there a way to script this?
thanks

Hello trader3000a,

You would have to come up with your own math for that for an open position. MFE is calculated on paired trades and is only part of the trade statistics which require a Trade meaning a entry + exit.

If there is some math equation that you have found which equates to the MFE of a unpaired trade you could certainly use C#'s math functions to do that.

Hi,
Ok, what's the most succinct way of asking for the highest high or lowest low since a trade has been in progress? BarsInProgress...since execution....??
thanks,
David

Hello trader3000a,


If its a filled entry you can use BarsSinceEntryExecutionto find that number, you would otherwise need to store the bar number when you submit the order so you can later find a BarsAgo buy subtracting that from the CurrentBar.

If you know the BarsAgo of the trade submission or execution you can use that as a lookback period for HighestBar or LowestBar

is there a way to get an entry execution's bar# from within an indicator?

Hello trader3000a,

Indicators are not associated with your strategy for trading so they would have no specific access to any of the strategy related properties. If you needed an indicator to know about that information you would have to make a user input for the indicator and then supply that information to the indicator when you call it in the strategies code.

Hi Jesse,
Thanks for your reply. I want an indicator that will display a dollar value in drawdown from a live trade's mfe. I'm not sure that's possible with my user-end tools. Perhaps we can put it in as a request for your dev team?
thanks,
David

Hello trader3000a,

Your strategy would need to call that indicator in its code and use AddChartIndicator to display the indicator on the chart. If the indicator needs to display a value from the strategy you would need to pass the value to the indicator when you call it from the strategy.

Hi Jesse,
I know i can generate the value in a ninjascript strategy. I'm saying I want to have the indicator as a stand-alone.
thanks,
David

Hello trader3000a,

A standalone indicator has no reference to your strategy, your strategy needs to use AddChartIndicator if you wanted the indicator to get strategy information passed to it. Manually adding indicators that a strategy is involved with would be bad practice, you should instead use AddChartIndicator any time you need to associate an indicator with a strategy.

Hi Jesse,
I'm no longer talking about a strategy. I'm talking about live discretionary trades. An indicator that tracks mfe against the live trade.
thanks,
David

Hello trader3000a,

You can use the addon framework to observe manual orders however there is no bar number associated with that information, you are just looking at the raw execution information in that case. You can read about the addon framework in the help guide: https://ninjatrader.com/support/help...ount_class.htm

If your questions no longer involve strategies I would suggest to stop posting in this strategy thread and create a separate question in the indicator or general development forums.

Hi Jesse,
Ok, great, thanks for the advice
