DislikedGood Day,
Please can you assist me with this Mt5 indicator that i am trying to code? its based on the below parameters:
1. Fair Value Gaps
2. Liquidity
3. Trend
4. Support and resistance
5. When all parameters are met, will display a Entry and Exit point based on 50 pips
Below is the code which has many errors when i try compilingIgnored
