Hi there Phil,

I could be regarded your “PRT support” as I too can not follow really what you all say. Still, you could investigate these possible misunderstandings (I imply them by mentioning “my” figures) :

Default of PreLoadbars is 200, I think.

Max of PreLoadBars is 10000.
(don’t ask me what will be used when you claim 66000 etc.).
Notice that there will be something going on with using several TimeFrames. Thus, the 10000 would count for 30 second bars, but also for 4h bars. This may even end up in drama because the base TF will be your 30s which may not allow to span (for) the 4h. Also see my little subject below, which implies something like 360 4h bars in 3 months of 20 trading days. It is even less when we see that no 24 hours continuous trading exists and it depends on the asset.

With 30 seconds TimeFrame, you will get something like a theoretical 3 months, which is theoretical because a. it requires V12, b. it requires PRT-IB(KR) and c. it requires the Premium version of PRT. The latter you can obviously have, but still saying because of a. and b. which do not seem to match. But tell that you are on PRT-IB and V12 and all is fine.

On the up side, you will be correct on your observation of the preloaded bars to be necessary in the first place. To many this is logic, but initially maybe not to you. But now it is, because you came up with it yourself, right ? 🙂
And notice that it is not always clear to see how much data a certain indicator requires. If you have a specific indicator you can ask – some of the geeks will know (I don’t).

Nah, not so. But don’t underestimate what happens at the brokers (especially IG) if things get volatile (like with FED news) and their systems and they themselves can’t keep up (huge slippage or no entry). One account is fine (because first in order), the other is not (never gets its turn).
And otherwise we still have the market’s workings. I buy at price X, so you will buy at price X+1 or not at all (Limit order).

Etc. ?

If I am wrong on some or everything, then apologies.

Default PreLoadbars is 2K.

Hi,

For IG PRT, what is the max PRELOADBARS?

I am using below in my prorealcode autotrading.

DEFPARAM PRELOADBARS = 40000

and I’ve a IF condition like

IF (BarIndex > 36000) and MyCondition

I’ve not seen my algo triggering a position with this condition.

If I remove “(BarIndex > 36000)”, then it does generate an order but with wrong values as calculation requires at least 36000 bars.

ps. sorry if posted in the wrong thread.

The problem is if the program gets stopped then you’re lost again. It has to start from scratch I guess.

I use “starting through” variables (Parameters) for similar. But where my application is relatively simple (it is for Money Management and when the system is thrown out), for you it would be more tedious because you would need to “prepare” averages by means of backtesting and have them as fixed “pre”-values in the code. They themselves must be integrated with the normal Average (etc. etc.) functions you use so all can progress over time.
Not funny, but thus technically solvable.

If I must restart a system with MM in there, it takes me 15-20 with shivering because of the mistakes and typos which can be made.
