Script or strategy makes incorrect calculations

• Script or strategy gives different results after refreshing the page (repainting)
• I successfully added the strategy on my chart, but it does not generate any orders
• Strategy produces unrealistic results on non-standard chart types (Heikin Ashi, Renko, etc.)
• I've added a script from the Community Scripts, and it is calculated incorrectly and/or I don't understand how it works
• I believe that the strategy is giving the wrong results
• Strategy produces unrealistically good results by peeking into the future
• My strategy processes orders one candle after the condition has been met
• My strategy ignores the ‘from_entry’ argument while closing entries
