Trading based on Number Systems - MT4/MT5 resources

This is actually 6 experts and they (my friends) have different ideas based on some numbering system. .
They call it a digital system? ? ?
1) 0.00333, 0.00666, 0.00999 systems ,, may be valid for EURUSD. . .
2) 11,13 systems , they calculate the sum of the price figures for any price let us say, 1.23400..
If it is 11 or 13, it is possible to enter or rebound the level! Weird! ! I never accepted that. . Not recommended either!

3) FIBO LEVELS (This idea is mine ).. round the price every 100 pips and then calculate Fibonacci numbers based on.. e.g. Fibonacci black and white 1. 02 and 1. 03

4) FIBO based on daily ATR

5 (FIBO based on weekly ATR

6) VLINES of S/R (STUDY button)
