Note that all indicators for the same symbol are read consecutively in the same thread. If one indicator slows down, then the whole symbol processing thread slows down as well
Slawa, of one symbol or on one chart? If there are several charts of the same symbol and different indicators are attached to them, are they all calculated in the same flow? Or is each chart in its own thread?
 

On Metaquotes-Demo limiters can have negative slippage - not correct.

How is it that there is no price, there is even a price in the log?!

Explanation

At first we tried to set BuyLimit at the lowest possible price 29528. This price is much higher than the Ask price (29038). In 99.99% of cases, BuyLimit is not set higher than Ask. However, it is not forbidden, so placing an order succeeded. And then (in purple) it took almost half a minute before BuyLimit became a position. Although it should have happened instantly. But to make matters worse, BuyLimit is executed at its price and not at Ask price. I.e., the limit order received negative slippage when it was executed, which is just a mistake!


The second OrderSend was an attempt to set BuyLimit as normal - not higher than Ask. And, of course, it didn't work out (in red). Because SYMBOL_SESSION_PRICE_LIMIT_MIN must not be higher than Ask.
