How many lots is maximum gun? How do you know it is not naughty noisy signal vs clean clear cut before placing bet?
how many lots?
It is based on the money management, and your trade plan (max loss per trade and per day allowable).
Usually (not always), when intermarkets move in tandem, and market move decisively, probability of success will be good.
In today case, simsci, Taiwan index, China A50, Hangseng, NQ, Nikkei, crude oil all moved together.
Interestingly today India Nifty went down alot for whatever reason.
But do note when market moves noisy jerkily and sluggishly,
with lots of poisonous spikes sprinkled everywhere , price movement could be alot.
Avoiding being injured by those spikes become very challenging.
