Good day to this thread! You know, the indicator compiles, but it doesn't draw anything, and I don't know what's wrong, what to think, how to look for a bug. Anyway, the code worked, I added a function to it with minimal changes, but now it does nothing at all!!!

Maybe the problem is somewhere in the declarations that begin with the grid, or maybe I'm too slow and messed up... It was working!

Thank you very much! So the EA trades on ticks, but can I change it to trade on intervals (candlesticks)? I am totally confused with it.

It is difficult to say, I have not done it that way. Maybe you need to somehow remember a bar or candlestick and if the next one appears, then... something is up. The code written inside the start function is executed on every tick, and what's already written there is what the programmer wrote.
Please answer the following question: let's assume two sell and buy orders open simultaneously with the same TP=SL =100 pips. The market went only in one direction and both TP and SL have triggered. Does the trader stay in the loss due to spread, or everything is zero? Since there are builds and askkens, we'd better ask you to solve this puzzle. It seems to me that it should be zero because we have to consider this spread when opening orders. Thank you.

No zeros. Definitely in the red.

If you (hypothetically) assume that you manage to open two opposite orders simultaneously, then you will immediately find yourself in the red, no matter which way the price goes.

No zeros. Definitely in the negative.
How much is in minus? If we make TP = 104 and SL = 100, will it be zero? TP=SL + 2*spread?
yosuf:
And how much is in minus? If you make TP = 104 and SL = 100, will it be zero?

Am I the only one who thinks you are trolling?

It's a normal question for a novice trader. Yusuf doesn't joke about such things. Don't forget that his newly acquired knowledge is still of a virtual nature.

Thank you, for a tested TP, the described option is an emergency, so, wanted to go to a clean zero in such situations. I do not need anything from the TA services, in principle, but as insurance against unidirectional movement, I think it can save. As it is, I expect volatility of the market within these limits of TP and SL.
