Some signals are only for managed accounts service so will tweet them lately so do not follow them.
It is highly recommended to use stop loss to avoid big losses.
Mostly signals will be close manually.
I generate signals with my own setups so their is no confirm time for signals.
I will update my signals on twitter.
Keep refreshing your page to get every new signals in time.

All signals are based on my own study so please trade with your own responsibility. It is better to trade on demo first for sometime. Strategies are collected from different websites so apply them on demo and make it more better for your trading.
