This script allows me to size up my trades based on account size and ATR. Default is Weekly ATR.

Inputs:
1) Account Size
2) % Unit of Risk
3) ATR Time Frame
4) ATR Period
5) ATR Multiple

The indicator will calculate a trade size for you (1000 = 0.01 lots) across all pairs adjusted by ATR.
1 Unit of Risk (%) is equivalent to ATR Multiple * ATR Weekly of movement.

For example:
Assume you have a 10000 dollar account.
You equate 1% of Equity to N*ATR of movement on weekly chart.
Suppose N*ATR = 100 pips.
Therefore, your trade size will equate to 0.1 lots.

This allows the trader to equalize the effect of equity fluctuations relative to any one given pair.
