I need help getitng around delayed Chart data

[cryfgg]

I notice the Bid and Ask tend to be ahead of the candle sticks printing on my tick chart. In other words, the candles on the chart is always trying to catch up the trade execution at the exchanges. Have this in mind as you read the following.

Let assume, I'm looking to execute a BUY-STOP-LIMIT trade at $10 when the following happens :

Condition

1. When Price crossesbleow $9.75
2. Enter Long BUY-STOP-LIMIT trade at $10

When I tried doing this manually, I get the error that price has already moved above $10. The delayed chart data (about one second or less) is significant enough to miss the timing of this trade manually.
To get around this delay, I wanted to create an automated strategy that will execute the trade automatically. However, I think I will run into the same problem, if I try to use "Low[0] < $9.75" because it will be waiting for the bar to print on the chart before executing the trade. Thus, I was considering using "GetCurrentBid(0) < $9.75". Is there a way to access the "Last Price" a trade was executed (so that I can use the condition "Last Price < $9.75")?

Your assistance will be appreciated. Thanks

Hi cryfgg, thanks for posting. The "last" traded price is represented in the Close array. The data coming from the data feed might be slightly faster than the visual representation on the chart (milliseconds apart). There should be no need to submit the order at 9.75 to get the order to rest at 10$. Submit the order at 10$ if the last price is below 10$. You can test this out in a script on the Sim101 account.

Kind regards,

I understand what you're saying but that's not the strategy I'm tying to execute. That's why in my post I mentioned using a BUY-STOP-LIMIT order type. Thus, my trade will only execute if <Price crossesbleow $9.75> and then reverses (crossesabove) $9.75 to $10 .my trade will execute at $10.

Hi cryfgg, thanks for the follow up. The order methods will not execute any logic or conditions. The strategy needs to handle the order submission based on price movement. The EnterLongStopLimit order takes a limit price and a stop price. This defines a range of price values you are willing for the order to get filled on. The price movement order entry decisions need to be made by the strategy. To do this, check if the price crosses 9.75 and then place the order at 10$ if that becomes true.

Best regards,

I will provide the limit price for the EnterLongStopLimit order in the full Ninjascript (I don't want to bore you with all the info). The question I'm really asking is what is the optimal way to check (per my example) if price has crossedbelow $9.75? Given that price will be moving extremely fast; it can crossbelow $9.75 and then crossabove $9.75 in less than 2 secs (before the Buy-Stop-Limit order is executed at $10). I want my script to be able to pickup the crossbelow $9.75 before it shows up on my chart, and automatically submit the Buy-Stop-Limit @ $10 in anticipation of the crossabove $9.75.

Here are the options i think i have:
1. Low[0] &lt; $9.75 ---&gt; will only work for very slow price movement or if the crossabove $9.75 happens 4 secs later.
2. GetCurrentBid(0) &lt; $9.75 ---&gt; I think this will work bcos it doesn't rely/wait on the rendering on the chart, but I don't know if it is risky (ex. bad BID/ASk data). Can you think of any potential risk.
3. What other options do you think I have?

Thanks

Hi cryfgg, thanks for your reply. The best way to check the cross above is to use the CrossAbove() method that we have documented here:

https://ninjatrader.com/support/helpGuides/nt8/NT%20HelpGuide%20English.html?crossabove.htm

The OnBarUpdate method gets called in a matter of milliseconds you can assume it happens instantly. You can test out the output of CrossAbove by printing out the condition e.g.

if(CrossAbove(Close, 9.75, 1))
Print("CrossAbove " + Time[0]);

To get the cross to trigger as soon as possible you would need to run the script OnEachTick. Please try this out and look at the output window for the prints.
