PlaceLimitOrder does not execute position at exact price set in SubmittedPrice in Linear Gradient

I was chatting with @pcharalampous on Telegram and he requested to open a call here.

An example back test at Pepperstone (I did this same test at Icmarkets and it has the same behavior).

As you can read in the code, we can see that except the first two "mother orders" are market orders, setting the base price for the children orders, while the next general flow is only used limit order. Except when it reaches a stop loss (line 320) that I use PlaceStopLimitOrder.

What is expected from this robot:

1) It runs OnTick;
2) Post mother order and set the price for the children orders;
3) When the position reaches the take profit, on the next tick launch a new PlaceLimitOrder at the same entry price of the closed take profit order;
4) When the position reaches the stop loss, in the following tick post a new PlaceStopLimitOrder at the same entry price of the order closed by stop loss;

Considering this premise, all executed orders that turned positions and had profit or loss, should be posted at the grid price.

As an example I send the following video from the link: "https:// drive.google.com/drive/folders/1iJoAdK8wwfjYvmfXsY5l-XkUkC3XE2r3?usp=sharing"  demonstrates that the "PlaceLimitOrder" orders are not executed at the price they should. Also at this link is the robot code and the set used.

The interval between orders in this .set is 5 pips.
In this video, the start price of the buy children orders should always end at 2 and the sell children orders should always end at 0.

I am at your disposal to chat, I know Spanish (as long as you speak it slowly). English for text, I'm learning.
