i too purchased it on last friday for 160 USD from Rollo, but it doesnt perform so well as per the snapshots shared in telegram group.. more over it opens two trades (1 is buy and another 1 is sell).. so trades are hedged in EA always... according to the market trade closes with the profit and other one stayed opened in the queue for days until market turns back....
Rollo generates license key uniquely with our mt4 id, it may not work with other mt4 id's... also he told that once after purchasing we have to change the setting once in 2 months for the support price of 200 USD per year to work more efficiently, otherwise it will work with default settings and profits will not be as much expected....
Hope you understand about thunderbird EA ver 10 from RolloFX
