OnEachTick vs OnBarClose

[CMillz]

I have a strategy I’ve written using Calculate = Calculate.OnEachTick but I think it should be Calculate = Calculate.OnBarClose

The code looks back 2 bars. It compares values in the prior bar (say bar[1]) to the bar before the prior bar (say bar[2]). In this sense, Calculate.OnBarClose should work fine. However, the entry is based on the current bar (say bar[0]) breaking the high or the low of bar[1]. Once that high or low of bar[1] is broken on bar[0], a “EnterLong” or “EnterShort” is true and the trade is entered. My concern on setting this to CalculateOnBarClose is, would the strategy wait until bar[0] closes before the trade is entered OR would the trade still occur on bar[0] once the high or low is broken?

The problem I am having now with CalculateOnEachTick is if I hit my profit target on the same bar as the entry, the trade fires again even though this new entry is beyond my profit target. My assumption is CalculateOnBarClose will fix this, but I need to confirm it won’t negatively impact the entry logic.

Thanks

Hello CMillz,

When Calculate is set to 'On each tick' use IsFirstTickOfBar in a condition to trigger actions when the bar closes.

This is if you want some actions to happen on each tick, and some actions to happen when the bar closes.

When Calculate is set to 'On each tick' barsAgo 0 (like Close[0]) will refer to the open bar that is currently building.
When Calculate is set to 'On bar close' barsAgo 0 will refer to the most recently closed bar.

Ok...Appreciate the response, but that definitely doesn't answer my question. I had reviewed all of the documents you attached previously before I even posted.

See the attached picture. The bottom of that pink shaded area is the profit target and the strategy is going long.

Notice how the first order (circled) enters at the proper level, then almost immediately hits the profit target. However, once the profit target is filled the strategy keeps buying and selling because the logic is true for the remainder of that 5 minute bar.

I don't want it to keep doing that, I only want it to trade one time. I tried OnBarClose and that doesn't appear to work.

Sorry picture wasn't attached it seemed

Hello CMillz,

OnBarUpdate will trigger for every tick. The actions that happen are up to your logic.

If you don't want an action to repeat, use a bool in a condition that prevents the action until the bool is reset.

Below is a link to an educational site on C#.

If you want an action to only trigger when a bar is closing, use a condition that checks for IsFirstTickOfBar (which is also a bool).
